Threats & Synergies
Not the strongest of engagers, but given how squishy you are you should still be careful when playing against him, especially if the enemy ADC can follow up. Harass him only once his abilities are on cooldown.
Has a strong early, but if you don't allow him to get fed he shouldn't be much of a threat. Try to get your jungler to gank you early, if possible.
Her slows and her R are very annoying to deal with, but otherwise she's not that much of a threat. She can't outpoke you so you should win trades, but if the enemy support has CC you should still play carefully around her.
His CC is easily dodgeable and the rest of his kit is not threatening in the slightest. You can harass and bully his ADC out of lane when he eventually leaves to collect chimes. Be mindful of his ult, though.
Hard engage, so bad news for you. Poke him only once his hook enters cooldown, and get E level 3 to disengage if he gets too close.
How dangerous Brand is depends entirely on how good the opposing player is with the champion, but he's generally annoying to deal with because of his poke. Be mindful of his combos and keep your distances with your ADC while his ult is off cooldown.
Braum is not at his strongest right now. His slows can be dangerous, but you can easily disengage with your E. Can be a bit annoying to stack up on mist because of his shield, but little else.
Caitlyn outranges you early and can trade back without punishment. Stack up on mists as quick as you can and avoid her traps at all costs and she should become a non-issue once the late game rolls around.
If you don't allow him to snowball, it should be easy to deal with this guy. Take advantage of his positioning when he moves to catch a spinning axe and try to CC him or poke him to proc your passive.
Don't bother trying to root him, as he can just Arcane Shift away. Not hard to poke and not hard to deal with in general, so he shouldn't be much of a problem.
One of your best match-ups. Very squishy and easy to predict, and should die quickly if you manage to catch her. If your ADC can follow up on your roots, she will either play extremely safe or feed.
Annoying poke, and if he catches you with his root you're dead. His weak point is his reloading time, however, and you should try to catch him after his fourth shot. Use your E to make his ult harder to land.
Easy to poke and not hard to kite, but be mindful of her late-game.
Short-ranged in comparison to you, but can be annoying if left to her own devices during laning phase. Try to get her killed early and she shouldn't be much of a problem.
Overall weak ADC. She's very easy to stomp during the early game, so if you manage to get a couple of kills on her she should be out of the game.
Her poke can seem overwhelming, but she's very susceptible to being CCd. If you have an ADC that can follow up on your roots, she should be a non-issue.
Hard to deal with in general because of his attack speed and his range. Annoying even if he's behind.
If you allow her to catch you, you're pretty much dead. However, she's very susceptible to poke and can't engage safely if she's under half health, so try to slowly chip away her health from a distance to ensure your safety.
Very strong early, but as long as you play safe and don't allow him to snowball you should be fine.
Can outpoke you early, but like with Caitlyn she shouldn't be a problem once you start stacking up on mist.
Annoyingly long range, but otherwise not that dangerous. As long as you keep dodging her skillshots and harassing her when her dangerous abilities are on cooldown, she shouldn't be hard to deal with.
Has nasty poke and a very dangerous ult. However, she's immobile, so she's very susceptible to CC and ganks. If you manage to land your W on her while she ults, she will have to interrupt it or get killed.
Her Black Shield counters your root and her Q+W combo can be very dangerous. If her ADC is paying attention, you can get killed fairly easily. Your best option to kill her or her ADC is to bait out her shield first.
As long as you don't misposition she shouldn't be much of a threat, but she's dangerous if paired up with a champion with a strong early.
Senna's worst match-up. Nautilus has everything Senna doesn't like to deal with: endless CC, ridiculous tankyness, long range, gap-closing abilities and a shield. Pick Grasp against him and play as safe as you can, as your only chance here is to scale.
Not only is his hook dangerous, but you won't be able to punish him if he misses because he's extremely mobile. He builds Umbral Glaive first item, so warding against him is also hard. Try to have your Q ready to heal yourself and your allies if his ult is ready and you'll significantly improve your chances of surviving him.
Very mobile and with annoying CC abilities, so be wary of him. He's melee, though, so you can still poke him and abuse your passive on him.
Even though she's a monster late-game, in lane Sona is just a healing bot. She has so little health that rooting her once will be enough to kill her. Try to stomp her early so she doesn't become too much of a nuisance after the lane phase is over.
As long as you dodge her abilities, she shouldn't be too annoying, but don't underestimate her. Buy an Executioner's if her heals are getting in the way.
Very annoying to deal with. Swain counters your whole kit, but he's not as dangerous as other engages because he operates at close range. Even then, he outpokes you and can nuke you if you don't dodge his hook (which goes through minions, by the way), so be wary of him.
His tankiness is absurd and he can protect his team, but if he's alone he's completely useless.
Easy to poke and bully. Just make sure you don't get caught by his E and you'll be fine.
Ironically one of your nemesis. Stand behind minions to avoid getting hooked, and try to get ganked once he and his ADC manage to push the wave.
Depends on all-ins to get kills. As soon as she jumps towards you, root her and disengage. Same thing if she tries to dive you.
Trade with him only if you've already rooted him, because his damage early is nasty. You outscale him, though.
Annoying, but you can outtrade her if you kite her. Careful with her invisibility, though.
Hard-hitting abilities that aren't easy to kite, but he's very squishy and immobile. Needs kills to be good late-game, so he will fall off if he doesn't get any.
As long as you avoid being hit by her feathers while trading, you should be able to bully her easily.
Xerath is one of 3 dangerous champions that can outrange you, but unlike with Caitlyn and Zyra it will take a lot more than a few mist stacks to get on his level. Play safe and try to CC him whenever you can once his abilities are on cooldown. Ask your jungler for a gank if needed.
Very easy to harass, but be wary of his gap-closers and don't let him snowball you.
When laning against Yuumi, you should get an Executioner's ASAP, or she'll become very annoying to deal with. Try to poke her whenever she's unattached. She's especially dangerous if paired up with a champion with a strong early.
Yet another champion that outranges you during the early game, so try to stack up on souls and avoid getting too close to his plants. Her poke is nasty and will force you to retreat if you try to proc your passive on her.
Both your slows and annoying poke capabilities can make you very hard to deal with in lane.
Two champions with very high range, if you're well coordinated you can bully the enemy botlane with ease.
Senna was made to play around Lucian's kit. Try to get him fed so he doesn't fall off late-game.
With this combination you can poke even tanks to death, or reduce their health so much that they become afraid of engaging.
Champion Build Guide
Who am I, and why should you listen to me?
Hello there! I'm a support main who started playing League around the time Senna came out in Season 9, and I fell in love with her almost immediately. I'm currently around 200.000 mastery points with her.
However, I've never found a guide that explained exactly how and why she works, and with the recent discovery of a new viable build, I've found that a ton of people are having the same problem as me, so I decided to write this guide! Hope you guys take something from this, even if it's just a little.
What is Senna good at?
Before starting to play Senna, you must first understand what exactly she can do for your team and what you should avoid doing when playing her.
|Squishyness: If Senna gets CCd, there's not really much you can do to escape. Even though some of her builds can get around her squishyness, they do so by sacrificing part of her damage, which is one of her strong points.|
OK, but what does Senna do?
Senna's kit is full of utility and it usually works best when you're surrounded by your allies, as all of your abilities either help them out directly or allow you to set up a kill for them. In this chapter I will explain exactly what her abilities do and how you can make the best use of each of them.
Senna's Passive Ability is Absolution. This ability has a lot of components, so I'll go through each of them individually to help you understand what all of them do.
- Wraiths: Enemy units that die near Senna will spawn wraiths, pet NPCs that you can collect by auto-attacking them. Each of them grants 3 gold and 1 stack of mist, but they despawn after 8 seconds if Senna doesn't interact with them. Enemy champions and large monsters are guaranteed to spawn one of these upon death, while large minions are only guaranteed to drop them if Senna doesn't land the finishing blow on them. Similarly, there's a 22% droprate for regular minions which gets reduced to an 8.33% droprate if Senna lands the last hit on them. Epic monsters drop 2 wraths every time.
- Mist: Senna can also stack her passive by auto-attacking a champion twice in the span of 4 second. Upon hitting them the second time, you'll collect a stack of mist and you'll deal 1%-16% extra damage, based on the target's current health. This effect has a small cooldown as well. This is your main harassing tool in lane, and you should try to proc it as frequently as possible. Remember that hitting your Q also counts as an auto-attack, so you can very easily poke enemy champions hitting them with both in quick succession, which will also gran you a stack of mist.
- Absolution: Every stack of mist collected grants Senna 0.75 bonus attack damage. For every 20 stacks, Senna gains 25 bonus range and 15% critical strike chance. Once the crit chance exceeds 100%, she gains 35% of the excess as life steal instead. As a rule of thumb, you should try to collect 20 souls before the 7 minute mark, and after hitting that powerspike you can continue to scale into the late-game with ease. It's very important that you continue to stack your passive, because Senna does not gain AD with level, so you need to continuously collect mist to stay relevant.
- Relic Cannon: Senna's auto attacks deal 20% bonus attack damage and grant a percentage (10% at level 1, 15% at level 6, 20% at level 10) of the target's movement speed as bonus movement speed for 0.5 seconds after your attack hits. This is very useful when pursuing a target that's trying to escaper your range.
Q: PIERCING DARKNESS
- Description: Senna fires a laser in the target direction, damaging any enemies by 40 / 70 / 100 / 130 / 160 (+ 40% bonus AD) and healing allies and herself by 40 / 60 / 80 / 100 / 120 (+ 40% bonus AD) (+ 25% AP). This ability also procs on-hit effects, including your passive.
- Usage: This is your main ability. The most important thing you need to know about it is that it is an auto attack reset, so you can cast it immediately after an auto attack to deal more damage in a short span of time, and even chaining it with another auto attack afterwards if the situation allows for it. This will allow you to outtrade most other supports and even some ADCs, and it's the optimal way to proc your passive to collect one extra stack of mist.
- Targetting: The targetting of this ability is a bit tricky, and may take a while to learn. The thing is, this ability actually has a bigger range than it allows you to target, so you will do damage to units that are outside of the targetting range. Use this to your advantage by targetting minions, towers, wards, your own allies or literally anything else that is targettable in the map to extend the range and hit enemies with it. One neat trick you can use for enemies that are out of range is to quickly set up a ward between you and your opponent, allowing you to target it and hit the enemy.
What runes should I take?
There currently are 2 viable Senna runesets, not counting the basic one you may want to use as a training device. They are both very different and both have their advantages and disadvantages, but as long as you manage to understand when to pick each one and how to use them optimally you should be able to dominate them in no time.
I'll no go over the two sets of runes you can use, explaining all the different options you have depending on your team composition.
THE OPTIMAL RUNES:
Keystone: Glacial AugmentThis keystone is the one that works best for Senna, because it allows you to proc your passive much easily during laning phase to stack up on mist by using your AA+Q+AA combo. As we've already established, you need those stacks to scale, so the ability to slow enemies to hit them again before the timer on your passive runs out is invaluable for Senna. Your objective with Glacial Augment is to stack your passive as quickly and frequently as possible to try and outscale your opponent.
You want to take this keystone against anything that isn't hard engage or tanks, as it gives you the highest damage output and helps you become more powerful in the late game. Take into account that you won't be able to survive being
Primary: Magical FootwearSenna doesn't really need to buy Boots of Speed early, so having Magical Footwear as your first primary rune is a smart money investment, as once you finish Umbral Glaive you'll only have to worry about buying your tier 2 boots.
Primary: Biscuit DeliverySenna's mana costs are painful to deal with in the early game, so we take Biscuit Delivery to mitigate those costs and ensure you can stay in lane longer. The health part of the item is okay, but you don't really need it considering you have a built-in self-heal in your Q. You can also buy the biscuits if you don't think you're going to need them, but I would keep them until level 6 or so just in case you need an extra mana boost.
Primary: Approach VelocityThis rune has been recently changed, and now it synergizes even better with Senna's W. Approach Velocity will allow you to bully enemies that have been rooted much more easily, so take it against lanes in which you know you'll be able to make good use of it, like against immobile champions such as Taric or Miss Fortune.
Primary: Cosmic InsightYou might prefer to take this over Approach Velocity because of the extra cooldown reduction. I take this rune if I know I won't get a chance to abuse the enemy botline too much, because on the long run it will be much more useful. It will also allow you to get free assists more frequently, since it reduces your ultimate's cooldown. If you use this rune, take it over Approach Velocity, as the other two primary runes are pretty much essential on Senna.
Secondary: Presence of MindEven if the second rune from the Precision tree is flexible, you always want to take Presence of Mind on Senna, as it gives you a much needed mana boost. This rune works with both of Senna's runesets, so make sure you take it each and every time. Take into account that you will need to get a couple of takedowns early to make the best out of this runs.
Secondary: Cut DownSince Senna was the only marksman to not receive a health buff on patch 10.11, Cut Down has become much more useful for her recently. Make sure to focus whoever has the most health to make better use of this rune.
Secondary: Coup de GraceThis rune can help you set up some kills, especially during laning phase. It's usually useful against tanky targets because it allows you to kill them easily, so it you're against a squishy lane wihout any healers you're probably better off getting Cut Down or Legend: Alacrity.
Secondary: AlacrityThis is going to be the most controversial of my suggested secondary runes. I've already explained that I like to run an Attack Speed offensive rune on Senna, so you would think it would be enough, but in reality the other two Legend runes are not very useful on Senna ( Legend: Bloodline is not very effective because of your low attack speed and Legend: Tenacity won't save you from being deleted if you're CCd), and picking Legend: Alacrity actually helps to mitigate one of her weakest points: her attack speed.
By no means does this mean this is the better rune on her, but I like to run it just to get an extra hits in during the late game. Take any of the other suggested runes if you don't feel comfortable with this.
THE EMERGENCY RUNES:
Keystone: Grasp of the UndyingThere has been a lot of discussion about this keystone. A lot of people thing it's OP and that it should be picked over Glacial Augment while other players state that it's not good at all and should never be considered. I'm somewhat in the middle of these, because even though I certainly believe it's overrated, it works very well when facing certain champions. It gives you a lot of extra health and defensive capabilities, allowing you to survive more and provide more utility while you're alive.
You should pick Grasp of the Undying when against heavy engage and/or more than two assassins on the enemy team. Your objective here is not to harass and poke your enemy constantly, but to survive lane phase without feeding the enemy botlane. Keep in mind that you won't do nearly as much damage as with the other runeset because you won't be able to proc your passive nearly as much, but in exchange you'll be way tankier.
Primary: Font of LifeNone of the runes from the first row are very useful to Senna, so Font of Life is the one we want to take. It will give your ADC a tiny bit of extra sustain in lane, and it's certainly more useful than Demolish and Shield Bash on a long-ranged champion that only has a shield in her ultimate.
Primary: Bone PlatingThis rune will give you more survability during lane phase, and it will make it so champions who like to hook you like Pyke or Blitzcrank have a rougher time trying to get their ADC to kill you.
Primary: RevitalizeSince we're aiming for survivability rather than pure tankiness with this rune page, Revitalize is our best option.
