The doorways between realms are finicky and seldom open, even to creatures as dexterous as cats. Yuumi watched as other yordles waited for days for the eastern star to align with a particular stone archway, or waded impatiently between marsh-lilies, seeking a silver blossom blooming from the mud—only then would a pathway appear. But Yuumi’s yordle, Norra, possessed the powerful Book of Thresholds, which allowed her to instantly travel anywhere depicted in its pages. When Norra opened a portal, she and Yuumi would gleefully dive into its glowing paper and arrive at their destination, joined a moment later by the book.

Yuumi never paid the book much attention until one starless night, when she returned home from luring moon-moths with her shinylight to find Norra missing. She saw the book on her master’s desk and flipped through its pages in a panic, noticing that some were torn out entirely. Unable to read its title, Yuumi cried out to it in distress, calling it, simply, “Book”. In response, the book wiggled, and Yuumi was surprised to learn she could understand thoughts amidst the rustling paper. Despite not having a voice, Book made itself loud and clear. Yuumi learned that Norra had gone somewhere so perilous, she had destroyed the portal as she traveled.

Yuumi knew she had to rescue Norra, and turned to Book for help. Each of its thousand pages led to a different location along the lines of magic that crossed the material and spirit realms. The page Norra had used to travel was lost, but Book might be able to get them close. Yuumi and Book would have to explore every possible threshold. She became Book’s unlikely Keeper, vowing to protect it with the courage of a lion—if it fell into the wrong hands, the doorways to Bandle City could open to all kinds of unsavory and ravenous intruders.

Yuumi and Book began their arduous journey, visiting dangerous and unfamiliar lands. Yuumi sought Norra’s scent on the wind, to little avail. While Yuumi would sometimes break from their search to follow the scent of a mouse or restore her strength with a quick catnap, Book was frustratingly cautious, grumpy over lost time and nervous about threats they might encounter. Nevertheless, Yuumi and Book were both determined to find their master and bring her home.

When Yuumi especially missed Norra, she often sought out other companions. One of her favorites was a door-carrying shepherd with thick whiskers and a deep laugh like a babbling brook. Yuumi rested on his shoulders for a time, protecting him from angry snow-spirits stirring up flurries in a hailstorm, while he brought her wriggling fish.

Eventually, Yuumi uncovered the scent of her master lingering in a vast Shuriman ruin. Digging deep into the sand, she unearthed a broken shard of blue pottery that looked like a piece from one of Norra’s teapots. Before she could burrow further, a ferocious beast surfaced from the sand, and Yuumi and Book barely escaped. She could only imagine the chaos if a creature like that ripped its claws into Book’s pages.

Though unlikely companions, Yuumi and Book have become fast friends, united by their love for Norra. Yuumi continues to search everywhere for signs of her master, so she can someday return to her life of napping in the sun by Norra’s side."

One of them bends and turns inside itself, lashing about until it twists into the shape of a mackerel. Around me, the other moon-moths spin in mid-air, all transforming into floating fish. Delicious—until the whole world turns upside down. Books cascade up from the shelves, landing on the ceiling with a dozen thuds. My Norra floats upward, still asleep. The fish flounder in every direction as we all fall up, up, up—

I wake up, blinking sleepily in a wooden box as moonlight shines through the slats. How in a mouse’s house did I get here? Oh yes. The tasty stink of fish fills my nose and I remember prowling the streets of Bilgewater, finding a crate of dried fish, then eating my fill before falling into a deep, belly-full sleep.

Before I can get comfy again, my stomach lurches and I’m knocked onto my side. Dozens of dried fish fall on top of me—just like my dream!—and my stomach purrs.

Book flutters in the corner as it tries to edge away from the falling fish. It’s always hinting that food is bad for its pages. I think dried-up-trees would be much improved with the smell of fish, but Book knows much more about dried-up-trees than I do, so I don’t argue.

I peek through the cracks between the slats. The floor beneath us creaks and shifts while, in the distance, moonlight flickers on the surface of the… ocean!

“Book, whyyy?!” I cry. “Naps never lead to bad things!”

Book opens and closes in exasperation. I don’t do water, and neither does Book.

I start to panic. Book rustles, reminding me not to worry—but it’s too late. I scratch and scramble at the wood in desperation, and I shred some of the dried fish by accident. This ocean is making me destroy my yummiest snack—it’s the worst type of water! I paw at Book’s cover, opening it to a frost-tinged portal that will take us far away from this watery nightmare. We have to escape somewhere, anywhere. Even somewhere cold.

I’m about to jump into Book’s portal when I hear a scream that sounds like tinkling bells and the brightest rainbows. A scream that makes my fur stand on end. A yordle scream.

I peek through the slats in the crate and watch as two human sailors drag a blue-furred yordle to the edge of the bustling ship’s deck. One of them has black chin-whiskers and the other is chubby, and both are smirking. They step over roped stacks of harpoons, fishing poles, spears, and coils of thick fishing wire. Must be deep-sea monster hunters.

“This little ’un is gonna fetch us a prize gulperfish, eh?” the first sailor says.

“I hear the biggest fish love yordle meat,” says the chubbier sailor. “Never tried it before, myself. Not a lot of yordles ’round Bilgewater.”

The blue-furred yordle squeals and struggles against them. “I’m not bait!” he exclaims, squeaking with each word. “I beg you, please release me!” The sailors don’t budge.

The whole ship tilts as a particularly large bump shakes my crate. “Ah, that’ll be the fish now. Time to fill our boat with gulperflesh!” says the first sailor, grinning. I don’t like his grin.

An enormous fin circles our boat, making lion-sized waves that bash the side of our ship. I feel Book tugging at me. I know it wants us to escape through a portal, to get away from the bad water right now before anyone sees us, but I hear the yordle cry out. I stick my paw through the slats in the crate and open the crate’s latch. I won’t leave a yordle alone to die. Not after losing my Norra.

The sailors watch the fin thrash around in the water. They don’t notice me as I leap from my crate like the quietest tiger and stalk them from behind.

The poor yordle is tied to a long fishing pole, which the sailors are dangling over the ocean. The water beneath him is bubbling and frothing. How does water always move in the worst ways?! I jump over the pile of harpoons and Book follows, flying next to me and nervously flapping its pages as it hovers in the air. They see us.

“Is that a purple raccoon—with a flying book?” one of the sailors asks.

“I think it’s a baby bear with a journal,” says another.

“No, you idiots, it’s just a cat,” says a third. “Get it!”

The sailors rush at me, but I dart swiftly between their feet. I unfurl a coil of magic that twists and tangles around their legs. They trip and topple like cups on a table.

I perch on the ship’s railing next to the fishing pole, unsure what to do next. The waves swirl below us, and my hunting instincts kick in—something’s gonna pounce.

“Untie me!” shouts the yordle as he clings to the fishing rod. “I am not a piece of bait. This is quite strange and embarrassing!”

Luckily for him, I am not afraid of fish. Even if I don’t like water.

I bound onto the fishing pole. In the midst of a cat’s leap, sometimes time slows. With my paws splayed out like pancakes and wind rushing through my fur over the terrible water, I am determined to save this yordle with everything I’ve got. Besides, mid-leap, there’s no going back.

“Don’t worry, small blue yordle!” I shout. “I got you!”

The yordle’s fate and mine intertwine as I land on its shoulder, with Book right behind.

The fishing pole wobbles under our weight. The biggest fish I’ve ever seen—a third the size of the boat—bursts from the sea with its mouth gaping open, hundreds of teeth glistening in the moonlight. Its jaws open so wide it could swallow a pair of cows, without even chewing them up. Even in the dark, with my shinylight I can see its skin is made up of pointed razor-sharp scales of silver and violet.

The giant gulperfish swallows us whole—the yordle, Book, me, and even a bit of the fishing pole, with room to spare.

We jostle against the roof of the fish’s mouth as it falls back into the water. It’s pitch-black, and smells like old seafood! Before it can gulp us down, though, I balloon open a magical shield that bubbles around us, lodging us in the fish’s leathery gullet. I blink on my shinylight again, illuminating some seriously rotten teeth that explain the awful smell. The yordle squeals at the sight. The fish lashes about, and the three of us are thrown in every direction, protected by the impermeable bubble.

What a strange way to make new friends!

I try to open Book so the three of us can escape, but the gulperfish leaps into the air once more, and we are tossed into a heap inside the bubble. We fall with a thud—the fish must have landed on the ship’s deck. I hear the sailors shouting as the enormous gulper thrashes back and forth, slapping them with its tail.

I hear a splash, and another, and another. The humans must have been knocked into the water. Still stuck in the throat of the gulperfish, I flip Book open to a portal that shimmers with the dusky green of Bandle City, the green of home.

I grab the small yordle’s shirt with my teeth and dive into the page. The portal widens and we spin into the spirit realm, dizzy and whirling into a jumble of colors.

We emerge, coughing, on the banks of a shallow creek. My lungs fill with the sweet air of Bandle City, thick and lush as in my dream. Sapphire-blue crickets chirp in the twilight as the brook babbles gently, full of fish—normal-sized fish.

Book flaps its pages to dry off. The blue-furred yordle stands up, dripping and shaking. “What was that? How did we… escape?” he asks. “Wasn’t the nearest Bilgewater portal back on the docks?”

“Lucky for us, Book carries our portals around wherever we go,” I say. Book twirls, showing off its dried-up-tree pages, each inscribed with a magical gateway outlined in ink and paint.

“Well, thank you for saving me, both of you,” says the yordle. He looks at Book curiously. “Is this where you’re from, too?”

“Yes, but we don’t live here anymore,” I say. I look at Book, sadly, thinking of master.

Book flutters. I know it thinks it’s time to move on.

“You know how to get home from here?” I ask the yordle.

“Yes, yes, just up the hill past the bowl-moles. I know this meadow well. And I do hope you find your yordle,” he says, before wandering off.

I stay for a moment, watching as the gloaming turns to daybreak. I catch a glimpse of a moon-moth hovering on the horizon and I long to pounce on it, but I remember that Norra is still lost somewhere, perhaps waiting for us to rescue her this very minute.

I pat Book as gently as I can with my paw—I know it misses her too.

Then I open it to a new page, and dive in."

Full Poke


Useful against sustain champions, even those with heaps of crowd control effects. Since you can't detach yourself a lot safely, your Q Prowling Projectile is even more important against those champions.


Full Healing
Useful against hard lanes with huge damage outputs and snowballing assassins in the enemy team (or lane camps). However, this ability order is a pretty mana-hungry one so make sure to rush mana regen items since these will become the foundation of your life-saving activities.

So many weapons Aphelios. The deadliest is your faith. Category: Okay

Playstyle Aphelios is quite good with champions that can peel (e. g. Leona, Nautilus or Lulu). You do have some peel with your ultimate Final Chapter but it's not that much. He's also quite immobile since he doesn't have any dashes or gap closers. This makes him quite vulnerable to hard CC and engages (e. g. Thresh, Blitzcrank, Rengar or Talon). In order to succeed in lane, you will have to make sure your passive Bop 'n' Block's shield is up whenever possible, as well as your E Zoomies. Your E Zoomies plays a keyrole in your gameplay since it provides him with additional attack speed whenever you're using it on him. Also, he will gain adaptive damage while you're attached to him. Try to keep the enemies at bay by playing aggressively, but not over the top. Activate your passive Bop 'n' Block's shield and keep diminishing their health bars with your Q Prowling Projectile while attached. I would probably try to max your E Zoomies first for the additional attack speed and overall healing but keep in mind that it's also very mana-consuming. Runes to match Since he is squishy and you might have to heal him a lot, I would go for Domination secondary for more lane pressure. The more damage you're able to dish out, the less you'll have to potentially heal him back up. And even if you'll have to heal a lot, the adaptive force of Eyeball Collection optimizes your healing since your E Zoomies scales with your ability power.

For a safer option, you can also consider picking Resolve secondary. Font of Life and Revitalize will work quite well with your kit as well. I would pick these runes when facing one of the following champions:
Blitzcrank, Leona, Nautilus, Thresh, Talon, Rengar, Ryze.
These champions can easily bursth the two of you down and/or have tons of CC.

Summoner Spells to annoy
I found that Heal and Ignite work best since you'll have more lane pressure and sustain. Aphelios can pick a second Heal, but Barrier is usually the better option here.


Items to improve the playstyle
Depending on which runes you selected, I'll split this point in two.

⟶ Domination's Eyeball Collection and Ultimate Hunter:
You will want to pick rather aggressive items, such as Rylai's Crystal Scepter or Twin Shadows (I usually prefer Twin Shadows for its passive but that's just a personal choice). If you're winning, you can also consider picking up Rabadon's Deathcap or Luden's Echo, even Liandry's Torment works. I know they may seem weird picks at first, but don't forget that your E Zoomies scales with your AP and your W You and Me! also provides the attached ally with a flat amount and a scaling percentage of adaptive damage. A Redemption for more sustain can also be helpful, depending on how much you have to heal and how the game is going.

⟶ Resolve's Font of Life and Revitalize:
Your main objectives will be to focus on optimizing your slows which will activate Font of Life. This will be achieved by building Rylai's Crystal Scepter and Twin Shadows. The last item kind of depends on your game. If you're going fine, you can pick more aggressive items, like Morellonomicon or Liandry's Torment. If you're behind, choose Locket of the Iron Solari or Redemption.

All the world on one arrow. Category: Ideal

Playstyle Ashe is not a bad synergy pick for Yuumi. She got quite a high attack range, a slow with her W Volley, a vision ability ( Hawkshot) and a stun with her ultimate Enchanted Crystal Arrow. Together with your ultimate Final Chapter you have a stun and a root that makes it impossible for the enemies to escape. Make sure the timing fits thought - try not to cast both of your ultimates at the same time. It's a pretty combo but the catch is that it's only available once you're both level 6, Ashe's ultimate Enchanted Crystal Arrow can be dodged/missed somewhat easily and the cool downs for each of your ability is not too high but once they're both on cool down you're super vulnerable. So make sure to deep ward (or at least use wards at all). Runes to match I would recommend using the aggressive runes ( Domination rune tree secondary) because both of your slows ( Ashe: Frost Shot and Yuumi: Prowling Projectile) work well together and you should be able to have heaps of harass chances. But if you feel better with a more sustained rune choice, feel free to pick the standard ones or even Revitalize and Font of Life from the Resolve tree as secondary runes. Summoner Spells to annoy For the Summoner Spells I would recommend picking something that gives you a bit of sustain if you've chosen the aggressive rune choice. Your spells in favor would probably be Heal and Ignite or Exhaust. I would prioritize Heal and Ignite because Ignite gives you a bit of more pressure. But picking Exhaust is a pretty reasonable pick as well. If you've chosen the standard or sustained runes, you will probably want to pick up Exhaust and Heal.

Items to improve the playstyle
Since you already got tons of slows on your kit, I would probably try and see if you can get something else on top, rather than another slow. Liandry's Torment and Redemption should balance your whole kit nicely - after all you're getting more damage and more sustain with those two items. If the enemies got nasty burst champions like a Katarina or a Fizz, picking up a Locket of the Iron Solari would probably turn out as a great item as well. If you're ahead and there are only little threats around, consider picking up a Morellonomicon for more damage or a Zeke's Convergence for more damage over time and some sustain.

I'm on the case. Category: Ideal

Playstyle Caitlyn is a lane bully which means she's got a lot of pressure thanks to her passive Headshot from level 1. If she's using her passive Headshot wisely and tries to farm while in brush, you can pretty much freely harass from there with Prowling Projectile. Together with her W Yordle Snap Trap, you're also being offered a free invitation to land your ultimate Final Chapter, once an enemy is caught in it. Caitlyn excels in early game while laning phase when she can abuse her range advantage and poke other enemies. So try to harass the enemies while you've got the upper hand and remember that your most important powerspikes is at level 2 when you're able to enable Zoomies. Now that it even provides your ADC with some juicy attack speed, your synergy with Caitlyn couldn't be any better. Runes to match Caitlyn and Yuumi both got amazing poke potential, so pick happily the aggressive runes from the Domination rune tree as secondary and head to the rift being as annoying as you can be! Summoner Spells to annoy Depending on the enemy team and their late game composition, I would go for Heal and Ignite or Heal and Exhaust, preferring the first option over the second. Ignite will allow you to have even more poke potential while Heal helps you to remain a bit more sustained. If you feel safe though, you can swap Heal for Exhaust.

Items to improve the playstyle
Since Caitlyn got the damage and a root with Yordle Snap Trap, I would try to enforce the slow on your side. For this Rylai's Crystal Scepter should be your second or third item ( Athene's Unholy Grail first, Ardent Censer second or third, depending on how your laning phase goes and how much healing is required). You can also pick up Twin Shadows instead or as extra, but I would usually prefer to choose between one of the two and pick up another item, such as Zeke's Convergence or Redemption for more sustain. If you want some more damage Liandry's Torment also works quite well on Yuumi.

Welcome to the League of Draven. Category: Ideal

Playstyle Draven mainly loves support s who can poke but keep him safe. He doesn't like those who stand there where his axes will come down eventually. With this said, you should probably already know why Yuumi fulfills all of his criteria easily. She will hardly ever stand in his way and she can provide him with both, poke and heal. In order to win early game Draven will most likely either expect you to harass the enemy ADC heavily in order to distract them from farming while Draven can happily CS or he will try to get some kills. Since Yuumi spikes pretty much at level 2 (you got three abilities available while all others only have two), this would be a pretty nice possibility to get your lane a little head start. Try out this combo while attached: > > AA > >  >  > Runes to match I would definitely go for the harassing runes with the Domination tree as secondary. However Dravens usually get countered by skill shot champions like Morgana, Lux, Nautilus, Blitzcrank or Thresh a lot. So positioning matters too! If you fear you might lose the lane, the standard runes will do too since they're a little more focused on sustain. Summoner Spells to annoy Ignite and Exhaust work best with Draven in my opinion because he takes received damage personal and you will want to lower the enemy's damage as much as you can. Playing with double Heal (him and you) on bot lane or him having Barrier works too, but I found Ignite and Exhaust as best option.

Items to improve the playstyle
A mixture of sustain and damage items will most likely do the trick here. Since you're not a Brand who can only rely on his CC and damage, you get to decide what's more important. Of course, I would always advice to pick up an Ardent Censer. Together with Draven's Blood Rush works Twin Shadows fantastically. You provide the slow with Prowling Projectile and Twin Shadows and he'll Blood Rush to the slowed enemies to finish them off. Liandry's Torment and/or Rylai's Crystal Scepter also work pretty well if you're looking for some extra damage.

You know you want me. Category: Ideal

Playstyle Evelynn is an assassin jungler who can stealth herself after reaching level 6. If you attach yourself as Yuumi onto her while Evelynn is stealthed, you will gain this ability too. It is the perfect combo to trap enemy champions, take out their carries and secure objectives this way. Make sure to not cast Prowling Projectile too early because it will give away yours and Evelynn's positioning. So be careful and aware of timing. Try to prioritize using Final Chapter against multiple enemies for multiple lockdowns. Warding also becomes a lot easier because you are simply hard to see and catch to the enemies, meaning if Evelynn decides to counter jungle near bot lane and your lane is pretty safe (like your ADC just recalled or the enemy jungler just showed up top), attach yourself and say thank you to the opportunity to place deep ward safely. Make sure to not leave your ACD alone for too long though. Runes to match Firstly, this depends mostly on your bot lane match up but if possible, I would go for the aggressive runes over safe ones. Evelynn is an assassin and every kill or assist she gets, you will get as well. She also has nice aoe's in her kit. Therefore Ultimate Hunter will give you allow you to lower your Final Chapter ultimate's cooldown.

Items to improve the playstyle
Basically, anything that slows champions add more per cent to potential kills. That's why I would advice picking Rylai's Crystal Scepter and/or Twin Shadows. If you have to choose on one of them, I personally prefer the Twin Shadows because you don't have to detach yourself from her. However, to activate your Passive Bop 'n' Block you will want to detach for a second and basic attack an enemy champion. Rylai's Crystal Scepter therefore works pretty well too. But I feel like Twin Shadows is a safer pick.
Finally, Ardent Censer will help you keep your little stealthy assassin healthy and able to get away. It works really well with the Ultimate Hunter and Eyeball Collection runes since you can use your ultimate Final Chapter more frequently and deal more damage to protect her more, while improving your heals with Ardent Censer and some stacks of Athene's Unholy Grail.

Quest accepted... Wait, where are you going? Category: Okay

Playstyle The thing about Ezreal is that he can jump around which makes it harder for you to land your Q Prowling Projectile. He's also mainly farming early and has no real lane pressure or wave clear. He's not a bad synergy pick for Yuumi but not a brilliant one either. So you mainly depend on landing your Q Prowling Projectile and some autoattacks while staying safe. Runes to match I would definitely go for the standard runes for this matchup. You really want the extra 5% everything, especially for the cool down, Cosmic Insight will grant you. Summoner Spells to annoy For a more defensive lane, I'd pick Heal and Exhaust and sit back waiting for potential all ins of the enemies and hope their accurancy isn't perfect. If you're not a fan of double Heal, have Ezreal pick Barrier. Ignite is another good option for him, but I think Barrier is a bit more valuable for the additional sustain.

Items to improve the playstyle
Even though Ezreal will want to take it slow, this doesn't mean that you'll only have to buy defensive items. Twin Shadows or Rylai's Crystal Scepter will allow you to provide some slows that might even start trades or team fights. However be careful since you're super squishy. Liandry's Torment for the grevious wounds passive would also fit nicely here. Otherwise Zeke's Convergence is also always another nice add-on that fits into you build swimmingly.

My heart and sword always for Damacia. Category: Ideal

Playstyle Garen is an off-tank and mostly played top. However, in season 9 in LCS we could see him as Guumi played as ADC with Yuumi. The reason this combo works so well is that Garen is pretty tanky and hard to kill which enables you to harass freely, while helping his passive Perseverance recharges him from possibly taken damage. Another huge plus point I've experienced is that Yuumi works really well with front liners in general: You can cast your Prowling Projectile and Final Chapter at maximum range while being safe with your ally. I laning phase make sure to harass your enemies with Prowling Projectile from early on so Garen can farm creeps without much annoyance. Your Zoomies will help you accomplish this. If the enemies got a quite poke heavy lane, the Guumi combo might not work best but you can consider putting some more points into Zoomies instead of Prowling Projectile. But do not forget that this way you will have less damage/poke. Runes to match This depends mostly if Garen is playing ADC or top. I would not bother so much about runes if he's top. If he's playing ADC, I'd check out the enemy team composition and their bottom lane. If they got poke champs like Zyra or Vel'Koz as enemy support, I would consider that standard runes. If their enemy lane consists of, for instance, Ezreal and Janna or Soraka, go for the aggressive runes since this is a matter of how much you will be able to poke back versus how much damage you'll expect to heal.

Items to improve the playstyle
Tanky champion means a lot of healing. But on the bright side, make sure your Garen gets a Spirit Visage at least as second item. You should definitely rush Ardent Censer and if the other lanes don't go too well or you're up against poke champions, I would advice to pick up a Redemption as well. Garen should want a Warmog's Armor in late game so he can enable you to heal your other team mates while you're making sure his HP bar isn't dropping too much. Don't try to heal him all the way up. You don't have enough mana for that anyway and with his passive Perseverance it would be a waste anyway. Your Passive Bop 'n' Block will work nicely on him in early and mid game but in team fights, I would focus on other allies in your team that are able to dish out some damage - like mid lane.

Twin Shadows works pretty well with Garen, especially if you're trying to catch up to escaping enemies. However beware of chasing them. Twin Shadows works pretty nicely in combination of your ultimate Final Chapter.

Summoner Spells to annoy
If you're going for Ardent Censer and Redemption, I would probably not go for Heal but Exhaust instead. But this depends on how much poke the enemy bot lane has.

Behold, the might of the Shadow Isles. Category: Ideal

Playstyle Hecarim will most likely be your jungler or in some rare cases top laner. So why bother adding him here? Because he's got quite an outstanding kind of synergy with Yuumi. He's usually euqipping Ghost instead of Flash and his ultimate Onslaught of Shadows slows and makes enemies flee. Perfect combination with your Final Chapter. Hecarim is a front liner who can start team fights, has enough crowd control to disable carries and is (mostly) tanky enough to get out of those trades somewhat well again. As Yuumi you really want to cast your ultimate Final Chapter from the best possible position which is most of the time a reliable front liner. It's actually really fun playing with a good Hecarim player. You can even provoke a team fight with your Q Prowling Projectile. Keep him alive and collect those kills and objectives! Runes to match Runes mainly depend on the whole team composition and what you'll face on bot lane. But if you can, aggressive runes ( Domination as secondary rune tree) would probably rarely prove themselves to be a bad pick. Summoner Spells to annoy This is mainly: Keeping your carry alive and helping him to dish out damage. So Heal and Exhaust or Heal and Ignite will be quite great spells to accomplish this. I'd recommend Exhaust over Ignite to keep the pony dancing and let less enemies escape from your insane combo.

Items to improve the playstyle
Hecarim likes to get himself into trouble by galopping right into it. Therefore, Redemption should be quite high up on your list along with some real nice items like Twin Shadows. The shadows will chase enemies and provide vision along the path they're traveling and what's more fitting to a champion whose home are the Shadow Isles? Next I can highly recommend Zeke's Convergence for it's passive.
Also, make sure that Hecarim himself is building Spirit Visage as soon as possible because it enhances your healing on him - it's an essential item for him.

In carnage, I bloom, like a flower in the dawn. Category: Okay

Playstyle Jhin is a pretty strong scaling ADC, however, he's got 4 charges of basic attacks with the last one being the strongest and then has to recharge. It's not something that makes him weaker necessarily but farming is a bit difficult for him and he'll want you to at least autoattack or land your Q Prowling Projectile on the enemies first so he can try to root them with his W Deadly Flourish. So basically you're both depending a lot more on one another than most bottom lane matchups. That's what makes it a bit harder but he's still strong. Another arguable point is that both of your ultimates ( Jhin: Curtain Call]] & Yuumi: Final Chapter) don't really work out too well with each other. That's why you should try to consider if it's worth casting your ultimate Final Chapter once Jhin rooted an enemy with Deadly Flourish. Runes to match Since Jhin is able to deal a lot of damage from early game on, especially with his last charged bullet, it's never wrong to be the lane bully and picking up the aggressive runes with Ultimate Hunter and Eyeball Collection as secondary rune tree choices. But I would decide that on how much of a threat the enemy bot lane embodies. Summoner Spells to annoy I would probably go for Heal and Exhaust here because if you can slow the enemies while Jhin ults them, it's just (hopefully) another earned kill.

Items to improve the playstyle
I would pick Twin Shadows because once the shadows caught an enemey, Jhin can cast his W Deadly Flourish to root them and you should be able to cast your ultimate Final Chapter if they're not dead yet. Make sure to go aggressive against enemies because Jhin needs to pick up some kills in early and mid game to not fall behind. Twin Shadows and Liandry's Torment provide a good and juicy harass for that. If you're being focused a lot (for example by a Malphite), picking up a Redemption and casting it as early as a team fight starts should keep your allies healthy.

Rules are made to be broken... like buildings! Or people! Category: Ideal

Playstyle Jinx is a late game hyper carry. But with her Flame Chompers! traps she's got a pretty good potential to get some early kills and assists as well and become a beast. With your poke Prowling Projectile she should be able to at least deal enough damage in early to farm enough to afford an early B. F. Sword. Zoomies will let you heal her enough to sustain the lane plus provide her with additional attack speed for a short amount of time. In mid and late game, once Jinx's passive Get Excited! is enabled, she will gain attack speed and an enormous amount of movement speed for a short while. This would be mostly your perfect sign to start you ultimate Final Chapter and chase down those fleeing enemies, get them locked down and then run for the hills again avoiding possible damage. So your main perspective with Jinx would be to keep her safe, enable her to farm creeps and prepare for late game. Runes to match Early game can be a bit annoying when you know your full potential will unfold much later. But with ideal synergies, such as Jinx, I would mostly advice the poke/aggressive runes over the standard ones: Domination> Inspiration in this case. If you feel safer with the standard rune choices, that's okay too, but you'll omit to potential harass. Summoner Spells to annoy Here I would chose an early game spell and a late game one. For early game, I would probably choose Heal or Ignite, depending on how much you fear the enemy bot lane. And for late, I would most likely pick Exhaust.

Jinx is a litte bit (yes, euphemism) crazy. So she might get into reckless situations. If the enemy team got a lot of poke, I would pick up Ardent Censer and an additional Redemption. The Redemption is not a must pick though. If the game goes well in mid game - this is were Jinx should have scaled enough to deal severe amounts of damage. In order to support her a little better, I would probably pick Liandry's Torment or a Rylai's Crystal Scepter if your early went okay. As mentioned above, if your Jinx tends to be a little suicidal or overerstimating herself a bit, pick up a Redemption, it should do the trick.

Since Jinx's passive Get Excited! already gives her a huge amount of movement speed over a short time, I would probably not go for Twin Shadows. However it can work well, especially if your team lacks gap closers.

Playstyle Kai'Sa is one of the best scaling ADCs in game. Her power spikes up in late game and her whole kit is pretty powerful itself. In return she's super squishy and vulnerable which means you should mainly focus on her getting fed, enabling her to buy the items she needs. Your priority will be to harass and slow the enemies as much as you can, so Kai'Sa can finish them off. With her Supercharge she gains movement speed which can be used as both, a welcome dash to kill the Flashing enemies or escaping a ganking jungler. Once Supercharge is upgraded, you can both enter a quite short time of invisibility. If Kai'Sa positioned herself well enough, this would be the perfect timing to cast your ultimate Final Chapter. Kai'Sa's wave clear is better than most ADC's which means you can dominate your lane by pushishg and forcing the turret down early (but make sure you've got deep wards here). You're not relying too much on ganks since your own lane pressure and kill potential is better than most other matchups's. On top of that, your E Zoomies will provide her with some scaling percentage of attack speed while used. It's quite powerful and works really well with Kai'Sa and her usual builds. Runes to match If you're not against some hard CC like Leona's or Nautilus's, I would go with the aggressive runes - Domination secondary - because your synergy with Kai'Sa is quite ideal. You will want to use your power spike at level 2 to make sure you have some lane dominance. Summoner Spells to annoy Since you wanna go for poke, Ignite and Exhaust should be the Summoner Spells you're looking for. If you feel that you're already sacrificing some potential sustain with the aggressive rune choice, you can go for Exhaust and Heal.

Items to improve the playstyle
If you're going for a full harass build, you should still consider picking up Redemption since it can be sometimes hard to heal the whole team - or at least keeping the carries alive. Aggressive rune choices that work quite well are Liandry's Torment and Rylai's Crystal Scepter or Twin Shadows. They will allow you to literally scratch and wound your opponents.

Death to all betrayers. Category: Okay

Playstyle Kalista is nowadays not a very popular pick and for a Yuumi that's nothing to be sad about because your synergy is not necessarily great when compared to other possible ADC picks. It's not overall a bad synergy but there are better options. So if you're playing with a Kalista, this means you should be safe from the feared skill shots that are one of your worst enemies. However, the hopping is somewhat of a disadvantage because it makes landing your Q Prowling Projectile and ultimate Final Chapter way harder. Also, a not well-thought hop from Kalista could make it impossible for you to reach an ally with you W You and Me! you might want to heal with E Zoomies. It might even expose yourself to the enemies unable to reach anyone in your team. For Kalista it's quite the same: With her passive item Black Spear she can't really bind you because if she throws you into the enemies with her ultimate Fate's Call, you way too exposed. So it is wiser if you don't even give her the choice to bind you in the early game and instead she binds the jungler who will hopefully actually gank your lane. Runes to match Because it's hard to rely on your Q Prowling Projectile, I would strongly advice to go for the standard runes and see that you'll live through laning phase and make sure to keep her and your other allies alive. Cosmic Insight will provide you with more cool down reduction which is great for your whole kit. But if you happen to dislike the Inspiration tree as secondary. The Resolve tree will perform as fitting alternative here with its Font of Life and Revitalize runes.

Summoner Spells to annoy
Heal and Exhaust should be the spells you will want to have short at hand. They will give you enough sustain for the lane and keep you healthy.

Items to improve the playstyle
For this synergy I would advice to pick up some more defensive items that are still really useful. Your choices should include Redemption and Zeke's Convergence for sustain, Locket of the Iron Solari for magic resistance or even Knight's Vow for armor. If the game is going in your team's favor, you can consider picking up some aggressive item of your choice. My favored one would probably be Twin Shadows because of it's passive I really value highly.

Will you prove worthy? Probably not. Category: Ideal

Playstyle Having Kayn as jungler is quite a good thing for you. Even though he can't be for too long in the front line, he can almost always escape by simply running through terrain with his E Shadow Step which also allows him to heal and pick up movement speed. This ability allows you with Kayn to engage and start team fights with your Q Prowling Projectile and/or your ultimate Final Chapter. But beware of his ultimate Umbral Trespass because once he casts it, you won't be able to stay attached with You and Me! any longer. This means you'll be exposed to the enemies if there aren't any allies around. So make sure you don't go onto suicidal missions with him. Runes to match It is quite difficult to advice runes when you don't know the rest of the matchup. However, if your lane looks more than okay to you, you can pick the aggressive runes choices. Otherwise I'd advice picking Revitalize and Font of Life from the Resolve secondary tree for sustain because Kayn's play style can appear to be somewhat suicidal for most situations that I've experienced. Summoner Spells to annoy With Kayn it's always a nice idea for go for Ignite and Exhaust because you're able to get close enough to get into reach to use these spells and they provide you with additional damage, vision (of the ignited enemy), damage reduction and a slow.

Items to improve the playstyle
Twin Shadows is probably one of my most favorite items for Yuumi because the two shadows its actives releases provide vision and can slow enemies who are in reach. This gives you and Kayn the opportunity to pick up enemies unexpectedly. Zeke's Convergence will provide you with sustain and some damage over time. You can pick up a Redemption if you're healing a lot, but keep in mind that Kayn is a champion who likes to charge into team fights and get out as quickly as he entered it.

Playstyle All Kog'Maw needs to make it to late game is some harassment for the enemies and some protection, like shields or heals. He doesn't mind CC. Yuumi got all of those. With Prowling Projectile you should be able to annoy the enemies enough to enable Kog'Maw some CSing. Your passive Bop 'n' Block provides him a shield he needs and you should make sure that it's up pretty much all the time. Zoomies will cover up for potential mistakes or damage he's taken in general. At level 6, with Final Chapter you should be able to kill at least one of the enemy bot lane players and thanks to Kog'Maw's big range of his ultimate Living Artillery he can harass the enemy ADC who is farming "safely" under their turret. Your both ultimates, Final Chapter and Living Artillery work pretty well together because once the enemies are rootes, Kog'Maw can clean up the rest with his. Since Kog'Maw doesn't have any gap closers, warding is really important for him. Ask your jungler for deep wards shortly before the enemy blue buff or a dragon spawns to prevent likely ganks. Runes to match I would choose the runes depending on the threat for Kog'Maw. For instance, if you face a Lux or Thresh as enemy support, I would most likely for the the standard runes. If you feel the threat isn't as bad, feel free to pick the aggressive Domination-secondary rune choice.

Summoner Spells to annoy
Same as for Jinx, I would pick an early game spell and a late game one. Since Kog'Maw is pretty squishy, I would probably prefer Heal over Ignite here. For late, I would advice picking up Exhaust.

Items to improve the playstyle
Kog'Maw doesn't have any gap closers. Therefore, he relies on you to land your Prowling Projectile to slow the enemy or you ultimate Final Chapter to root them. Twin Shadows or Rylai's Crystal Scepter will be a huge help here.

So prolong his life, it's probably wise to pick up a Redemption after Ardent Censer. But this is an optional one.

Playstyle Although Lucian has a pretty strong early game, he's not the best champion to play with. His E dash Relentless Pursuit can be both, either an incredible gift or a bad curse because he can use it to get in place for your skills (Q Prowling Projectile and ultimate Final Chapter) or mess them up. So be careful here. Lucian's passive however got a real nice poke potential that can be well integrated with your Q Prowling Projectile. You should make sure that you're zoning the enemies off their minions but not trying to create too many trades in general because your sustain is okay but not overly brilliant - you can't compete against a Leona with hard CC or a Soraka with her huge sustain. Try to harass but don't overdo it. You will want to keep about half of your mana at all times to deny ganks or all ins on you. Runes to match Since you should be winning early game (hopefully), I would recommend the aggressive runes, unless you're up against some massive lane bullies (e. g. Brand or Lux) or champions with better wave clear than you (e. g. Kai'Sa or Sivir). But if you're unlucky or simply counterpicked with wave clear champions, I would probably go for the standard runes with Cosmic Insight and Future's Market from the Inspiration rune tree. Against lane bullies, I recommend choosing Font of Life and Revitalize from the Resolve rune tree as secondary.

Summoner Spells to annoy
The Summoner Spells of your choice should be Heal for more sustain and Exhaust for the additional slow and damage reduction. Ignite can be a nice alternative, but usually Lucian keeps you out of range to use it and you're not the best synergy together because he falls off in late.

Items to improve the playstyle
Early game matters. His passive Lightslinger combined with the slow from your Q Prowling Projectile have massive harassment potential in lane. Use it. If you're winning your lane, you can consider building Liandry's Torment or Twin Shadows as second (after Athene's Unholy Grail) item instead of rushing Ardent Censer next. But beware of ganks and use deep wards to deny them.

If your early doesn't go according to plans, you should definitely build Ardent Censer second and consider going Redemption as third item. Twin Shadows can help you pick up enemies or escape from them quickly - Lucian isn't a champion who likes long trades, he's rather quickly in and out of team fights. A Knight's Vow can also prove itself as helpful, especially against teams that are building armor against you and your team.

Playstyle Having Malphite in your team (not on bot lane though) is a great thing, especially when he's your jungler. His ultimate Unstoppable Force is one of the best initiatives to start a team fight. Once it has been cast, be quick and cast your ultimate Final Chapter right afterwards. This way none of the enemies will be able to escape - or survive. Malphite's Q Seismic Shard is pretty similar to your Q Prowling Projectile which enables you a super long slow if cast right after one another (not at the same time!). Runes to match Since you're likely not playing with Malphite in the same lane, it's a bit difficult to recommend runes. But he's pretty tanky and since you will want your front liners to live long enough through team fights to enable your carries to deal enough damage, I would probably pick the Resolve rune tree as secondary with its Font of Life and Revitalize runes. Summoner Spells to annoy For Summoner Spells, I've found Exhaust and Ignite as really helpful. Whenever Malphite has cast his ultimate Unstoppable Force and you're casting yours right after, you will probably want to attach to him. This will enable you to get close enough to the enemies and use your Summoner Spells on them.

Items to improve the playstyle
For tanks, I like to pick up Ardent Censer as second and Redemption as third item. Make sure Malphite will build Spirit Visage to keep your mana at a healthy level. Twin Shadows or Rylai's Crystal Scepter work well to enforce the slows, however I prefer Liandry's Torment over both items for the extra damage over time. Zeke's Convergence works well too, but keep in mind that you shouldn't bind it to Malphite if he's not something close to 15/3/something and going full AP. A Knight's Vow would be a better choice in my opinion.

My blade is yours. Category: Okay

Playstyle The reason I decided to add Master Yi here was because he can be really good with you but it clearly depends on his early game phase. If he's having a bad one where he's being counterjungled and behind, then his comeback potential is quite low. But your both ultimates ( Master Yi: Highlander and yours: Final Chapter) can turn games around if used correctly and you've got a team that follows. With Zoomies you should be able to keep him alive enough to carry. Yuumi also won't detach herself from Master Yi when he's using his Q Alpha Strike. Runes to match Definitely aggressive runes since you will both need all the damage that's available. Domination with Ultimate Hunter and Eyeball Collection will provide you with exactly that. Summoner Spells to annoy Master Yi is easy to be killed once he's stunned or grabbed. Heal will give you the additional safety option, along with Exhaust lowering the enemy's damage. You can pick Ignite instead of Exhaust but usually Master Yi is fast enough to kill everybody in a blink of an eye.

Items to improve the playstyle
Master Yi is an assassin which means he rushes in, executes champions and rushes out just as quickly. Usually, picking up a Redemption is somewhat useless in that matter, but you two aren't in the team alone, maybe it can help your ADC or mid laner.

Twin Shadows is often way more useful, because it indicates where enemies are and gives vision of the paths it travels along. Furthermore it will provide you with some magic damage that will enhance your poke.

What really works well with Master Yi is Knight's Vow because of it's passive that converts taken damage of your bound ally into true damages to the enemy. If you don't want to go for a tanky item but for more damage Rylai's Crystal Scepter or Liandry's Torment should serve you well.

Fortune doesn't favor fools. Category: Okay

Playstyle I really like Miss Fortune but with Yuumi, you're not facing the greatest synergy. She's more looking for a Support with more CC, like Morgana or Blitzcrank. Miss Fortune is really susceptible to ganks or other hard CC (like Braum's) which you can't help deny for her much since this is your weakness too. What's great is that both your ultimates work well together: The root of your Final Chapter will allow Miss Fortune to hit every rooted enemy with her Bullet Time. Her Q Double Up provides her with a lot of poke that also works well with your Q Prowling Projectile. So you do have some lane pressure but do not forget that you're both very vulnerable to ganks - so make sure to ward accordingly. Runes to match Since Miss Fortune isn't your most favored synergy pick, I recommend the standard runes with Cosmic Insight and Future's Market from the Inspiration tree. Summoner Spells to annoy I like to pick Exhaust for the sustain and Ignite for the additional lane pressure you will not want to give up on.

Items to improve the playstyle
Rylai's Crystal Scepter provides you with additional slows from your auto attacks that will activate your passive Bop 'n' Block. It's also really nice because you will have more poke damage.
Redemption will give you some more sustain if needed.
As third item, I would choose it depending on the enemy team and their builds. If you need some magic resistance, Locket of the Iron Solari is a solid pick, for armor Knight's Vow will do and for more harass and magic damage, you can pick up a Luden's Echo or Liandry's Torment, even a Rabadon's Deathcap will serve you in this matter.

Playstyle Even though Pyke and Yuumi both got nerfed, their synergy is still ideal and brilliant. Stealth, invisibility and camouflage always work extremely well with Yuumi and on top of that Pyke received additional movement speed when entering his camouflage with his W Ghostwater Dive. When attached with your W You and Me!, you will become camouflaged as well with him. He can pull (Q Bone Skewer) and stun (E Phantom Undertow). His ultimate Death from Below and its passive 'Your Cut' will work in your favor as well and contribute to your gold and the possibility to get even further ahead. Runes to match If you've got a Pyke in your team, always choose the aggressive runes. The two of you have enough potential to carry from mid game on. The Domination rune tree as secondary with Ultimate Hunter and Eyeball Collection will provide you with additional cooldown for your ultimate Final Chapter and more aggression potential, thanks for to the adaptive damage of Eyeball Collection. Summoner Spells to annoy Assassins are incredible hard to keep alive when they're suicidal or overestimating their own strength. Heal will help you keep up healing the amounts of damage he's taking. Depending on your laning phase and the enemy team, I would choose between Exhaust and Ignite as second Summoner Spell. Ignite can be a priority pick but I would have to lie if I said that Exhaust hasn't saved so many of lives in my gameplay yet.

Items to improve the playstyle
Your priority picks for items should be Athene's Unholy Grail, Ardent Censer, Twin Shadows and Redemption. You should be able to create fear wherever you show up, picking up kills and assists alike. A nice thing to pick up can be a Mejai's Soulstealer right after the Ardent Censer. Sell it once you wanna complete your full build with one of the following:
Depending on how you go, you can choose between Zeke's Convergence, Knight's Vow and Locket of the Iron Solari for sustain or Liandry's Torment, Luden's Echo and Rabadon's Deathcap as last item.

Justice takes wing. Category: Okay

Playstyle Quinn is a rather uncommon ADC pick and she's seen better times in jungle, too. Her ultimate Behind Enemy Lines allows her to unite with her falcon Valor and allows her to enter total movement speed. With this, she can roam with you along her side. The only problem is that you will want the paths you're both traveling warded. Deep wards will help you out, check my warding chapter in case you want more information on this matter. Quinn and Yuumi both are super squishy and while Quinn is in her ultimate Behind Enemy Lines she is also vulnerable to crowd control effects which will interrupt it. If this happens you two have no escapes or crowd control ( Yuumi's ultimate Final Chapter won't help you much sadly). Runes to match Quinn isn't your preferred matchup partner or pick in general. You both got some harass and some good mobility but that's it. So you will probably want to pick some rather standard or utility runes. I would recommend the standard runes Cosmic Insight and Biscuit Delivery or Future's Market from the Inspiration rune tree as secondary. Summoner Spells to annoy For Summoner Spells, I would recommend using Exhaust and Heal as safety options. Exhaust will make sure the enemy carry can't deal too much damage and they will be slowed. Heal keeps you both healthy and gives you a slight and short movement speed enhancement.

Items to improve the playstyle
Quinn wants you to have more crowd control, you want Quinn to have more damage. You can help out with more crowd control with Twin Shadows as slow and Redemption as heal. Zeke's Convergence or Knight's Vow can be nice defensive options. If you want some more aggression potential, you can pick up a Rylai's Crystal Scepter.

You know you want me. Category: Ideal

Playstyle If you have a Rammus as jungler in your team, you're somewhat lucky because he's super fast thanks to his Q Powerball, he's tanky and his E Frenzying Taunt. This will allow you to time your ultimate Final Chapter really well and your Q Prowling Projectile will make it even harder for any of the enemies to escape. Runes to match Definitely go for the aggressive runes if possible in cooperation with your lane matchup (depending on the synergy with your allied ADC and the enemy bot lane). Any additional harassment potential will only favor you, you can pick up items for safety later. Summoner Spells to annoy Summoner Spells should be picked in consideration with your laning ally, if possible though, pick Ignite since it's strong enough to cancel out most healings and deals damage over time. Exhaust can be a great additions in order to keep him safe and lower his need for healings. Heal is not that powerful on tanks since it's only healing flat amounts of HP and not any amount of per cent. But again, you should consider what your ADC will need too.

Items to improve the playstyle
Ardent Censer should definitely a priority pick after your Athene's Unholy Grail. If your Rammus has to tank a lot of damage, you should pick up a Redemption and encourage Rammus to build Spirit Visage because it enhances your heals even more. Usually I recommend Twin Shadows and it's a nice item but thanks to his Q Powerball it's not really needed. I would advice choosing Zeke's Convergence and either Liandry's Torment for more ability power and damage over time or Knight's Vow as more sustained variant.

Tonight, we hunt! Category: Ideal

Playstyle Another camouflage champion with the ideal synergy. Rengar's ultimate Thrill of the Hunt will allow him to enter the camouflage and gain movement speed and true sight. Being able to cast your ultimate Final Chapter out of nowhere is awesome because you will be able to hit as many enemies as possible with it. You can detach with your W You and Me! once it's safe and enemies are rooted to enable your passive Bop 'n' Block's shield, then attach yourself again to Rengar to heal him with Zoomies and slow enemies who attempt to escape with your Q Prowling Projectile. The only thing that might stop you are Control Wards. So make sure the enemies don't have those out, otherwise Rengar will have to look for alternative routes. Runes to match For ideal picks the aggressive rune choices are highly recommended. However, take into consideration your laning phase, which means the synergy with your ADC and the bottom lane matchup. You will want to make it safely out of laning phase to enter mid and late game and pick up those juicy kills with Rengar. Summoner Spells to annoy Ignite should be first on your list for it's damage over time and visibility control. You can choose between Exhaust and Heal next. Exhaust will lower the enemy's damage and provide a slow which makes it even harder for them to escape. I would probably favor Heal though, because Rengar is pretty squishy and you will not want to lose him and his damage - therefore, the additional sustain is quite needed.

Items to improve the playstyle
Ardent Censer is one of your key items along with Athene's Unholy Grail. Twin Shadows is an awesome item to pick up enemies. As the two shadows trail along their automated path, they allow you vision and will slow two enemies in reach. Furthermore, it will provide you with more ability power.
I really like Zeke's Convergence for more sustain and it's passive, as well as Liandry's Torment for even more damage. Redemption can be a nice sustain pick but remember that Rengar is moving a lot in team fights in order to not deny potential crowd control effects against him and focus in general.

I always take my toll - blood, or gold. Category: Okay

Playstyle Sivir has one of the best wave clear abilities in game. She can push like crazy and farm forever. But that's mostly it. She's considered a pretty safe champion pick thanks to her E Spell Shield which denies any kind of ability even with crowd control effects. If an ability hits her with her shield active, the shield will decay and Sivir will regain some mana. Her ultimate On The Hunt is the actually only thing that makes your synergy with her okay. Thanks to the movement speed it enables, you both will be able to make sure that all enemies needed will be hit and rooted by it. Your laning phase will be pretty safe but also might be somewhat boring for you. Runes to match The standard rune choices should do here, unless your jungler is one of the ideal matchup picks, like Hecarim, Evelynn or Twitch/ Kayn. Cosmic Insight is an awesome rune for utility. Summoner Spells to annoy I recommend picking Exhaust and Ignite for sustain and damage. They are great choices in case you're facing lane bullies (like Brand and Kai'Sa) and will keep you safe. Heal is okay to pick too, but Exhaust usually works better than double healing plus Zoomies.

Items to improve the playstyle
With Sivir's ultimate On The Hunt, Twin Shadows work really great. The item provides you with ability power and it's amazing active that are two shadows trailing a path to reach the nearest two enemies and providing vision along their way. If enemies are hit by these shadows, they will be slowed. If Sivir then uses her ultimate On The Hunt you should be able to pick up kills.

If you're struggling to hold the lane, Redemption is surely a great option in regards of itemization. Otherwise Zeke's Convergence or Knight's Vow are nice sustain items. If you're looking for more ability power because your team is doing well and you got an ideal synergy champion in your team, I can recommend Rylai's Crystal Scepter and Liandry's Torment.

Once a Bandle gunner, always a Bandle gunner! Category: Okay

Playstyle Tristana is a nice and jumpy ADC but she prefers rather lockdown types of supports - like Leona or Brand with actual stuns. She'll have to wait until level 6 for your ultimate Final Chapter to at least get a root. Otherwise she will have to pretty much initiate trades in lane otherwise with her W Rocket Jump. You can help her time it with your Q Prowling Projectile's slow. It's possible that she jumps out of a team fight or trade while you're casting your ultimate Final Chapter which might ruin it. If this happens to you in a team fight, try to attach yourself with your W You and Me! to another ally, preferably a front liner. Runes to match It's hard for me to advice the perfect runes for this matchup without knowing the enemy bottom lane's constellation. If you're facing lane bullies (like Vel'Koz and Lucian), go for the Resolve option with Font of Life and Revitalize as secondary rune tree options. If your lane looks okay otherwise, I would probably pick the aggressive runes and try to be the lane bully myself. Summoner Spells to annoy Even though Tristana can jump out of trades, I would recommend going for double Heal and picking Exhaust for a sustained option since this is not an ideal synergy partner.

Items to improve the playstyle
For items, I would definitely consider picking up Twin Shadows because you'll gain some more ability power which will allow you to gain more lane pressure and its active can turn games around if Tristana uses her gap closer W Rocket Jump for pick up some easy kills together with your Q Prowling Projectile's slow for infinite slows (they're not actually infinite but they'll feel like that for the enemies). Liandry's Torment is probably another ability power pressure item. If you're looking for more sustain, Redemption or Zeke's Convergence should be on your list.
