Champion Build Guide
Introduction
Hi everyone. I'm TheMistCollector, TMC or Mist for short. as you can guess from my name, I'm a Senna OTP, since she was out on PBE. I started playing at the end of season 7 and I got to Plat last season, it's my highest rank ever, and my goal this season is to reach Diamond (UPDATE: I DID IT :D next goal: Masters UPDATE 2: YOOO I'M MASTERS BABY UPDATE 3: GRANDMASTER, I'M GM UPDATE 3 I GOT TO CHALLENGER!!!). I know, it's not such a good elo (IT IS NOW), but the fact that she's the first and only champion that i mastered, and i have a lot of free time, I consider myself experienced enough with the champion to bring you a complete guide on her with no flaws.


Before Senna, I was a Support main, but i've always enjoyed Marksmen playstyle. When Senna got revealed, i knew she was my champion. I was there day 1 analyzing and theorycrafting with Senna, along with others... So yeah, i feel like i really know about this champion.
Btw this is my first time making a guide, so sorry for any inconsistencies and for no fancy table of content and all of that.
THIS GUIDE WILL GET CONSTANTLY UPDATED, any big change that affects Senna will be addressed. Additionally, i'm constantly theorycrafting new items and builds, if i find something OP, i will share it.
Also, english is not my main language, so if you don't understand a section of the guide or you find a small typo, please let me know!
(Apologies for the format getting kinda messy towards the end of the guide for mobile users).

Runes
In this chapter i will talk about the standar runes for
Senna, as well as some other popular (but not necessarily good) ones.
Fleet Footwork: Welcome to
Cut Down meta! Fleet Footwork is the only keystone here that Senna can blindly use. It gives a MS burst which is nice for an immobile marksmen, and the heal helps her play a bit more aggresively. The main reason we go for this though is because of the access to
Cut Down. In 12.12b, Senna became the champion with the lowest base HP of the game with 530 (
Yuumi has 550... 13.1b UPDATE: Good news, Senna is no longer the champion with the lowest base HP in the game, bad news, it's not because she got buffed, but because
Yuumi got nerfed. Basically, her HP is still low even if it's not the lowest one anymore). Because of this, Senna is the best champion to use
Cut Down, and we should always use it when building for damage.
Lethal Tempo: After the 13.4 AS ratio buffs (from 0.3 to 0.4), this rune is now viable on
Senna. I'd now say she uses every on-hit effect pretty effectively including this one. She stacks it consistently and the AS she gets is pretty good. Because she already has 600 base range, once it's stacked she can easily keep hitting champions in laning phase to keep the stacks and have 30-42% AS "permanently" alongside the extra range for your Q. After laning phase, this rune also has a really good scaling so you get a lot of extra DPS. I don't think this rune is that good to completely ignore Fleet, but it's good enough to risk your laning phase to use the rune for lategame DPS. Since ADC Senna doesn't want Fleet as religiously as Support/Fasting, this will be the best Standard keystone for her.
Press the Attack: This is an alternative rune in scenarios where
Fleet Footwork is not needed and you will constatly fight early 2v2s. Senna can proc this rune pretty fast with
Piercing Darkness and from a safe distance to not only boost her own damage, but her allies' too.
Presence of mind: This is still a good rune if you're building tanky, you don't need survivality and/or fights are going to be long. After testing ADC Senna without this rune after the mana buffs, i came to the conclusion that she still needs it. Without the support item's mana regen, and with the fact that she naturally uses more mana than her support counterpart because she has to deal with minion waves, means you cannot use Overheal.
Alacrity: This rune synergizes a lot with
Senna's kit. It increases both her DPS and Healing, since
Piercing Darkness cooldown gets reduced by 1 second for each auto attack. You also get Alacrity stacks by picking mists (only from the ground, not by poking enemy champions) so it scales much faster than any other ADC.
Cut Down: Explained it in the
Fleet Footwork section, but basically Senna has the lowest base health on the game so this rune increases your damage by a lot.
Absolute Focus: Alongside
Gathering Storm, they provide an insane amount of raw AD, which would usually only mean damage for every other AD champ, but for Senna it also increases her Q healing and slow. You don't really want to use other runes as Support, since this is the one that brings the most value to the team.
Nimbus Cloak: Alternative choice if the enemy team relies too much on MS. Swap this rune over
Absolute Focus.
Gathering Storm: Read:
Absolute Focus.
Conditioning: Rune taken for ADC/Fasting Senna if she needs the mid-lategame resistances.
Overgrowth: Only other usable rune if you're going for Resolve secondary and you're not building tank (if you don't need unflinching). It might take away some
Cut Down damage but
Revitalize's healing is barely noticeable if you don't have other healing effects.
Revitalize: Rune used in the Hybrid build against poke. You can use this rune here because besides increasin Q's and R's Healing and Shielding (which is usually not worth it), it also increases
Fleet Footwork and
Locket of the Iron Solari.
Taste of Blood: Used in ADC/Fasting Senna when fighting for the early game. This rune allows you to trade more aggressively and benefits from buying AD.
Treasure Hunter: Used in ADC/Fasting Senna when fighting for the early game. This rune allows you to have a faster snowball and a bigger payoff for winning early game.
Grasp of the Undying: Default rune for the Tank build, it helps with lane pressure with its healing and bonus damage (both scaling with max HP), but the main reason we go for this rune is the infinitely stacking Health. It's just an amazing synergy with the Tank build which is mostly Health stacking.
Guardian: Alternative, and weaker, keystone for the tank build. We lose a lost of synergy but there's going to be matches where you just cannot stack Grasp, so this is better than nothing. At least it also scales with Health, although not that much.
Font of Life: Another amazing rune that synergizes with Health stacking. It works great with out kit too since Q can slow in AoE.
Conditioning: This one has the best value mid-late game, but you will be trading a lot of early game survivality for it. If you're not confident in your laning consider going
Second Wind or
Bone Plating instead.
Revitalize: This is much better than
Overgrowth, since even though the point of the tank build is to stack health (and
Overgrowth seems like the best choice to tie everything together),
Revitalize helps to accomplish the same (have increased healing and survivavility), but it also affects other healings/shieldings that don't scale with health, like
Piercing Darkness and
Dawning Shadow.
Presence of mind: This is still a good rune if you're building tanky, you don't need survivality and/or fights are going to be long.
Alacrity: This rune synergizes a lot with
Senna's kit. It increases both her DPS and Healing, since
Piercing Darkness cooldown gets reduced by 1 second for each auto attack. You also get Alacrity stacks by picking mists (only from the ground, not by poking enemy champions) so it scales much faster than any other ADC.
First Strike: This rune is good on its own when building lethality, offering a small ammount of damage in the early game, growing as the match goes on. But the main reason we use this rune is for a number of facts combined, but can easily be explained with 1 word: Gold. First strike converts a portion of the damage dealt with it into gold, it allows us to use the
Inspiration tree to access
Magical Footwear and
Future's Market, and because we're building
Youmuu's Ghostblade, we can delay boots up to 3 items later to get our powerspike faster than everybody else in the match (this also means getting a faster use of
First Strike). All of this combined with
Spectral Sickle's fast gold generation, Senna's
Absolution further inflating our gold (with 8 gold per mist we pick up from the ground), and our fast early spike with a
Serrated Dirk to start getting early takedowns means that you will either be toe-to-toe with the enemy bot if you're in a naturally bad matchup, ahead in a naturally even matchup, and take over the game in a free matchup.
Magical Footwear: Read:
First Strike.
Future's Market: Read:
First Strike.
Cosmic Insight: Because we're building early damage, and delaying our boots, getting at least a bit of defensibility from this rune will be better than the more aggressive
Approach Velocity. Becuase Senna only uses defensive combat spells, having it +
Flash up more times is the best defensive rune we can get here.
Zombie Ward: Used when going for the AD stacking build, since
Umbral Glaive is a core item.
Eyeball Collection: Used When going for the lethality build. More AD is good.
Treasure Hunter: AD items are hard to afford with a support budget, so combining this with
First Strike is crucial to both snowball and keep up with the game the longer it goes.
Ultimate hunter: It's not worth taking it because Senna is not really reliant on
Dawning Shadow. It's true that
Senna's Ultimate has a lot of cooldown, but losing
Precision tree for a couple more ultimates is not worth.
Triumph: Ignoring that this rune scales with Max HP (and Senna has the second lowest), it is also meant to be very Skirmish/Bruiser heavy since it allows you to sustain better throughout the whole fight. If Senna wants a defensive rune,
Overheal Will be better, since it she's most likely either at full health, or dead/out of combat; you cannot afford to have survivality dependent on getting takedowns.
Cheap Shot: While it looks good on paper, when compared to
Taste of Blood you realize that the latter is better (Not by a lot, but still better). They both look to gain early advantages, one via damage and the other via healing, but ToB scales infinitely better and it is easier to proc.
Coup de Grace:
Cut Down DEALS MORE DAMAGE IN 105% OF THE MATCHES AND I'M NOT ONLY TALKING ABOUT SENNA (BUT SHE'S ONE OF THE BEST USERS BECAUSE OF HER EXTREMELY LOW BASE HEALTH), BUT EVERY MARKSMAN. STOP PICKING THIS GARBAGE RUNE!
Demolish: You outrange its proc range starting at level 1, so it's awkward to use from the start. Besides, the value of
Font of Life in a health stacking build is too good to pass up.

Summoner spells
In this chapter i will talk about the standar summoner's spells for
Senna, as well as some other popular (but not necessarily good) ones.
Flash: This is the best summoner spell in the game, by far. It can be used both aggressively and defensively, and can be used with other abilities (mostly
Last Embrace and
Dawning Shadow) to create unpredictable situations for the enemy team. Not taking this summoner spell is trolling.
Barrier: This is the standar summoner spell for support, because double
Heal is a bad option. it helps for general survivability. If your ADC doesn't go Heal, consider picking it if you don't need
Exhaust.
Heal: This is the standar summoner spell for farming and fasting. It helps for 2v2 early fights and for late game survivability. Go for this if you don't need
Exhaust or
Cleanse
Exhaust: This is a good alternative. It is meant to counter assassins and skirmishers. Against these champions it's always more valuable than
Heal, since it shuts down burst damage.
Ghost: Great alternative in matches where Movement Speed will make a great difference. It can be used both defensively (to disengage from a fight, to avoid a gank, etc) and aggressively (to chase down a target, to have better kite, etc).
Cleanse: This is a great summoner spell meant to counter heavy CC (
Ashe,
Leona, etc.) or any undodgeable CC (
Twisted Fate,
Annie, etc.). I always prioritize this over
Exhaust since being CCd means that anyone can burst me down anyways. (avoid using this when playing support, unless you when don't need neither
Heal nor
Exhaust)
Ignite: This is NOT a good summoner on Senna, doesn't matter the role. If you are at Ignite range, you are poorly positionated.

Abilities
In this chapter I will show every ability of Senna, as well as giving general information and tips.
In a nutshell, Senna's auto attacks have reduced attack speed, deal reduced crit damage, doesn't use a proyectile, gives her movement speed and deal additional on-hit damage. Hitting an enemy champion with an auto attack or damaging ability 2 times grants Senna a Mist stack. Each Mist stack gives 0.75 AD, and gives 20 range an 10% Crit chance per 20 Mists (excess crit chance grants Lifesteal instead, up to 35%). Mists can also appear when a unit dies near Senna (chance is different for each unit, also affects if Senna is the killer.)
This is your main ability, you use it to trade, for high DPS and huge healings in teamfights. If you have enough range you can pretty much hit all 10 champions with every Q, so think about your positioning.
This ability is just a generic CC, you can use it to escape, lock a target, follow up a target or opening a follow up to your allies. You can also use this ability when warding to check brushes without risk.
This ability is the most tricky ability to correctly use.In the early game, you can use it to chase, you can use it when your duo is walking from base towards the lane to surprise the enemy, you can walk towards river and bring your jungler to an easy gank, you can use to scape ganks/all-ins (
Ashe can't kill you without
Enchanted Crystal Arrow if you have E for example).
In late game you can use it to catch isolated enemies with a teammate, or it can be used as an overall pressure since the enemy team don't have any information. This ability is super flexible! how you use it will make a huge difference between a noob Senna and an experienced one.
You want to use this ability in teamfights where you can hit the most amount of champions. It has a huge cooldown, so try to save it when close to important objectives.
Since it's global, you can also use it to snipe any enemy who got out with 1 HP. You need good coordination / high map awareness.

In a nutshell, Senna's auto attacks have reduced attack speed, deal reduced crit damage, doesn't use a proyectile, gives her movement speed and deal additional on-hit damage. Hitting an enemy champion with an auto attack or damaging ability 2 times grants Senna a Mist stack. Each Mist stack gives 0.75 AD, and gives 20 range an 10% Crit chance per 20 Mists (excess crit chance grants Lifesteal instead, up to 35%). Mists can also appear when a unit dies near Senna (chance is different for each unit, also affects if Senna is the killer.)
General tips:
- This is the most important ability in Senna's kit, since you don't have AD per level, it's important to have a high Mist per Minute ratio. 4 Mists per Minute (40 mists at 10 minutes. 100 mists at 25 minutes) when Fasting, and 2.5 Mists per Minute (40 mists at 16 minutes. 100 mists at 40 minutes) when Farming are good indicators that you're doing good.
- 40 Mists is a generous powerspike since you gain a lot of gold worth from stats (~1500 gold) and the 40 additional range makes you a much scarier threat.
- You can lifesteal out of Mist wraiths
- Ally champions who kill minions with
Relic Shield or
Steel Shoulderguards are considered killed by Senna for Mist Spawn Chance purposes.
Q - Piercing Darkness
![]() |
![]() |
When to use:
This is your main ability, you use it to trade, for high DPS and huge healings in teamfights. If you have enough range you can pretty much hit all 10 champions with every Q, so think about your positioning.
General tips:
- You should constantly AA anything (if minions, make sure you don't mess up the wave for your ADC) because it reduces Q cooldown, allowing you to trade more oftne
- This ability can reduce its own cooldown when used against: Enemy turrets, enemy champions, jungle plants and enemy wards, meaning if you Q into AA against any of this things you will reduce 2 seconds of cooldown in no time.
- This ability cannot reduce its own cooldown when used against: Ally turrets, ally champions, ally and enemy minions, ally wards, jungle monsters (dragons, buffs, small camps) and mist wraiths.
- If you hit your Q against both a target that reduces its own cooldown and one that doesn't, regardless of target, it will still reduce it.
- If your Q hit multiple enemy champions, it will reduce its own CD by 1 second for each enemy champion hit
- You can use Q to clear enemy wards faster
Sheen and other on-hit effects procs based on enemy Spawn ID.
- This ability is currently BUGGED (12.19 last check): If you use it while channeling
Dawning Shadow the Q will go towards the ultimate's angle, not the Q target.
W - Last embrace
![]() |
![]() |
When to use:
This ability is just a generic CC, you can use it to escape, lock a target, follow up a target or opening a follow up to your allies. You can also use this ability when warding to check brushes without risk.
General tips:
- You can W +
Flash, the ability will be casted to target location from after-flash position. There is a bug that, when timed correctly, will make your W projectile look like its going from pre-flash position, but its hitbox is actually from after-flash position, making it look like it goes through enemies and suddenly hits a random target.
- You can look to kill a low hp minion close to an enemy champion with W to surprise them with an instant root
Malzahar's
Void Shift will block W damage, but not the root (as long as he is the main target).
E - Curse of the black mist
![]() |
![]() |
When to use:
This ability is the most tricky ability to correctly use.In the early game, you can use it to chase, you can use it when your duo is walking from base towards the lane to surprise the enemy, you can walk towards river and bring your jungler to an easy gank, you can use to scape ganks/all-ins (


In late game you can use it to catch isolated enemies with a teammate, or it can be used as an overall pressure since the enemy team don't have any information. This ability is super flexible! how you use it will make a huge difference between a noob Senna and an experienced one.
General tips:
- This ability is a big part of why Senna is annoying to play against, you can hide your whole team before a teamfight so the enemy team can't engage on anyone.
- In the early game, you can trick the enemy botlane by walking to the sides while your duo walks towards them to engage. (HIGH COORDINATION REQUIRED)
Control Wards reveal you. after leaving the ward's area, you will be revealed for an additional 1.75 seconds before camouflaging again
- If there is a
Control Ward out of vision while in E, it will be revealed, so you can take it without risk.
- You can use this ability when warding to get that extra survivability and movement speed, since squishy champions struggle to ward without being in heavy danger.
- This ability is currently BUGGED (13.7 last check): Seemingly random abilities can target you even when you're camouflaged. Instances that i have found:
Katarina's
Shunpo,
Nami's
Ebb and Flow,
Zyra's plants,
Aphelios'
Onslaught.
R - Dawning shadow
![]() |
![]() |
When to use:
You want to use this ability in teamfights where you can hit the most amount of champions. It has a huge cooldown, so try to save it when close to important objectives.
Since it's global, you can also use it to snipe any enemy who got out with 1 HP. You need good coordination / high map awareness.
General tips:
- This ability DOES NOT DAMAGE ANYTHING BESIDE CHAMPIONS. Don't try to steal objectives.
- The shield scales with total number of mists.
- You can R +
Flash. The ability will always shoot from the original cast position. Senna will face towards the same original direction, but if you time it perfectly, she will actually face towards the blink direction (similar to
Ezreal's
Trueshot Barrage +
Flash combo). So use it to trick enemies (very situational)
Combos
In this chapter I will show main combos that you should know to make this champion easier. Keep in mind that Senna is not a combo oriented champion and these are just simple things.
AA + Q - Basic trading/poking combo
![]() |
You will use this combo A LOT in laning phase. It's an easy combo meant to deal decent damage and collect a mist from the enemy. |
Q + AA - basic long range trading/poking combo
![]() |
This is a variation of the first combo, it's meant to use your Q to its full potential by using it on minions and hit an enemy at max range, then follow up with the AA for the mist. |
W + Q - Basic mid range pickup combo
![]() |
This is an easy combo meant to catch opponents by casting W with an immediate Q for the slow. You can start hitting AAs after that |
Ward + Q - Advanced long range pickup/finisher combo
![]() |
This combo can be used with 2 purposes. First, you can use this combo to catch an enemy at max range with Q's slow, and you can also use it to kill an enemy out of range. |
W + Ward + Q - Advanced long range pickup combo
![]() |
This is also a combo to lock champions out of range. You W at max range, and then Ward+Q to slow them for an easy W hit. |
W + Q + AA + R - Advanced mid range execute combo
![]() |
This is the most damaging combo. It's used to burst down a single target (or more if your W roots multiple enemy champions). Try to use AAs every time you can for maximum damage. Be sure to time your R when the enemy is rooted, as they could use ![]() |
Synergies
In this chapter I will explain Senna's synergy with different classes of champions.
TANKS
![]() |
By far Senna's best synegry. They are very forgiving so ranged enemies will not be as punishing as it looks. They also carry a lot of CC abilities so they can peel Senna in case of assassins or bad early trades. Their high resistances make Senna's healing more effective. |
FIGHTERS
![]() |
Also a really good synergy. they usually have great built-in sustain so ranged enemies are not a problem either. Their all-in is better compared to tanks but they struggle to get on top of the enemy botlane. |
MAGES
![]() |
Overall an effective synergy. They can keep up with the range of the enemy botlane. They have a decent early game but without a lot of kill pressure. |
SUPPORTS
![]() |
Also a solid defensive option. they are made to help other teammates so there's no adaptaion problems. And it may doesn't look like, but supports with full wave income can be very scary opponents. You will not have a lot of damage in the early game, but you have will have great teamfight potential. |
MARKSMEN
![]() |
Terrible synergy. They are meant to deal DPS and have no tools to help teammates. If you want to play alongside a marksmen, play support. |
ASSASSINS
![]() |
By far the worst synergy for Senna. They get destroyed by a ranged botlane, they have no tools to help teammates, and they have really different objectives compared to Senna. Never pair these 2 together |
Fasting Tier list

This is a Tier list of Senna's best Fasting duos. It is all in order, meaning that if a champions is above another in the same category, it is better in my opinion. I will now explain every tier:
S - Best
Best champions for Fasting Senna. Conformed by champions with good utility, damage, and tankiness and some specials interactions. If you want to climb with someone playing Fasting, you should start learning at least 1 of these champions.
A - Good
Still really strong picks, but not as good as the first tier. This champions are still an amazing pair with Senna but they might have a problem or two keeping them out of the "Best" tier, like not having enough peel, not having a good wave management or struggling against a double ranged botlane.
B - Average
As the name says, just average picks. The synergy is there, but it's nothing amazing. Some of this champions may feel outclassed by other above them, or they have some problems that are too noticeable to place them in a tier from above. I don't recommend trying to learn a champion from this list, but they're playable if you already now the champs.
C - Below Average
Niche picks. They work but with a lot of problems. Should be saved for specific situations or if you find the champions fun to play.

Matchups Sheet
It's finally here!

Sorry for taking so long, but i wanted to make it right (It has gotten like 3 mayor overhauls before the actual release, lol). Right now (13.9) it's only for Support Senna, but i'm still working on ADC and Fasting. (13.10 UPDATE: a couple of hours after the update of this guide, i will drop the ADC matchups)
I have a Changelog in which i explain my future plans each update, so be sure to check that if you have any questions.
Anyways, enjoy! Click the text below to access it.

Items
THIS SECTION NEEDS A HEAVY REWORK, PLEASE IGNORE THE SPECIFIC BUILD ITEMS AT THE START AND ONLY FOCUS ON "GENERAL ITEMS" ONWARDS.
In this chapter I will talk about every item viable on

Crit Build:
Core items:
Kraken Slayer - AD scaling True Damage, insane AS.

This item, alongside ![]() ![]() ![]() |
Guinsoo's Rageblade - High AS, special interaction.
![]() |
This item is the perfect combo for ![]() ![]() ![]() |
Hybrid Build:
Core items:
Locket of the Iron Solari - High resistances, underrated passive/active.
![]() |
This is a great tank item. it's really cheap and it makes you surprisingly tanky. The aura, although unnoticeable, it's always there making your teammates just a little bit more tankier. The active is kind of insane, and because it also affects you, that's another extra tankiness. Another important part about this item (and also the reason double resistances shards and ![]() ![]() ![]() |
Lethality Build:
Core items:
Youmuu's Ghostblade - Insane stats.

If you want damage, this is the best Lethality Mythic choice. Because of their lower stats, you only build ![]() ![]() |
Manamune - High AD and Mana.
Situational items:
Axiomic Arc - Standar Lethality

Edge of Night - Vs. Skillshots(and more)
Tank Build:
Core items:
Radiant Virtue - Highest HP item
![]() |
![]() ![]() ![]() |
Spear of Shojin - Standar HP + AD item. Special interaction.
![]() |
I'm still not sure if this item will be considerable at all once the BC bug gets fixed, but for now i'm gonna recommend it. The item has the perfect stats that Tank Senna wants (AD, HP, conditional MS), and it also has an amazing interaction with her. Spear of Shojin has AD scaling AH in one of its passives. With Senna, this means infinitely scaling AH. Build this item as support right after cores if you don't need ![]() |
General items:
Black Mist Scythe - AD poke starter
Boots of Swiftness - Standar.
![]() |
Situational boots when MS will make you survive more than standar resistance boots. Either the enemy team has a lot of skillshots, or they're very melee with not a lot of ways to get on top of you. Build these boots when the extra MS will outvalue either ![]() ![]() |

Early game
General tips
At the start of the match, do not stay for the Mist after leashing your jungler, unless they clear insanely fast, like a 3 box shaco.
After backing, if you find your jungle clearing Gromp (red side) or Krugs (blue side) you can go near them to get free mists.
I do not recommend using E to get to lane faster. The cooldown is way to big, it's important to have it up when needed (also the MS is not even that big).
In a straight line of enemy minions, and at 0 extra range, Qing the first caster, or the cannon in a cannon wave, will make

If you start fighting a 2v2, always try to hit all 3 champions with your Q to get the most value out of it.
You can kill a low HP minion with W to root enemies close to it to make an unexpected engage
You can use E to help your jungler gank (or your midlaner if they roam) for an easy and deadly surprise to the enemy botlane.
You can also use E if your botlane partner is coming to the lane after they backed to hide them and opening up an easy engage.
A tricky thing you can do with E is to approach the enemy botlane alone to scare them into thinking you have an ally with you, so they're forced to retreat. You can use this to get some farm or to regain control of the lane while your botlane partner is not present.
Farming/ADC
Your early game is generally bad, but it's super safe because of your range and self-peel. Your objective in this time of the match is to use your range to safely farm, or to poke down the enemy botlane whenever possible. Your safest way to poke as ADC is to Q a minion (ally or enemy) to hit an enemy out of range, to then follow up with an easy AA because of the slow and

Fasting and Support
Your early game is quite decent, but you can really struggle against counter picks. Your main objective in this time of the match is to poke, poke and poke. Poke whenever you can to get tons of mists and gold. Constantly harass the enemy ADC when they try to last hit a minion. Your Q is really powerful when trading, you can force an AA trade with the enemy ADC, then using your Q to heal his damage, while dealing a bit more to them. As Fasting Senna you can take 1-2 melee minions per wave additonally for the best gold-mist balance. You can also use the Q+AA combo in hard matchups to get an easy mist out of range.
For Support only, you also want to roam, but less compared to any support, since Senna likes to stay just a bit more on lane because of her Mists. I usually roam when:
- I'm in base and my ADC is dead/gone, i'll just walk to another lane or river.
- An objective is up and my jungler wants to contest, either herald or drake i'll be there.
- I'm in botlane and i can't gain vaule from anywhere there because of an enemy freeze or similar, i'll walk to midlane, or if it doesn't look gankable, i'll go deep ward the enemy jungle.
Mid game
General tips
Senna's mid game has a little problem: since the laning phase is over, there is no way of getting consistent Mists per Minute. The map below shows places where you can be to get mists from both the camp and the wave if it's crashing near the spot. Blue and Red are the colors of the team, but you can use the opposite if the map has enough pressure. Yellow dots are places where you can get mists from multiple camps if allies are clearing them, not really dependant of waves.
It might sound like niche information, but i assure you, it happens a lot more than you probably think.

Besides the mists issues, Senna has a solid mid game because you already have a decent range to be a scary threat, and also because of your big impact in objective teamfights and skirmishes.
Farming/ADC
Your midgame should be strong, with Kraken+Guinsoo you deal quite a lot of damage from a safe distance. Your main objective in this time of the match is to set up lanes for Dragon or Herald, without risking your life. Don't overextend to push one more wave, your team will probably lose the objective fight without you. Also remember to ward, it's not only the support's job.
With the Lethality build this is your strongest point (besides hyper late game), but in a different way. You're not that good in skirmishes and teamfights because your DPS is not that high, but what you can do is harass the enemies in-betweem fights with your spells without having to commit, since you have better burst damage than the crit build, so that they can never enter a fight at full health. Use the same tricks of poking in the early game to damage the opponent over and over again when they go to push a lane, or when you find them in the jungle.
Support and Fasting
Your midgame should be strong, whatever build you're using, with the amount of mists that you have collected, you're super strong in healing and dealing DPS from a safe distance. Your main objetive in this time of the match is to set up wards and clearing enemy wards arround river and the Dragon/Baron pit when they're about to spawn. You can also help other laners to push lanes faster or to win map priority. If needed, you can back to get pinks and reset your support item, it doesn't matter if you don't have anything else to buy. try to avoid being in a lane by your own, you can die pretty easily.
Read the ADC/Farming last bit to understand more what you have to do in the Mid game when you play with the Lethality build when Fasting.
Late game
General tips
Your late game is awesome, so much damage, so much healing, so much RANGE. You're a monster, and you should play like one. And no, i'm not saying you go all-in 1v5, just play safe like any other ADC, keep your distance of assassins and any close range threat, and keep yourself alive for as long as you can, while dealing insane DPS.
Farming/ADC, Fasting and Support
Same as Mid Game, but with a much stronger teamfight potential, if you die by overextending or poor warding, your team will lose the most important champion of the match, and will probably lose the game. Don't get excited for beign a damage monster, you're still a piece of paper, and everyone wants to shut you down.
With the Lethality build you're not that much of a monster, you're damage will fall off considerably in teamfights. Poke as much as you can in-between fights to get an advantage, but it's going to be a lot harder compared to mid-game.
Last bit of info and Conclusion
phew, that was a ride, i swear i could talk about this champion for hours. In fact, this guide was started in January (2021), i had a couple issues with coding at the start, and a couple of breaks in between, but it's still a lot of time, i really feel like i said everything that i know.
JK! here is a list of quick minor information
Ok, now i think that's everything i know. Feel free to discuss anything you disagree in the comments, and one of us will learn something about it. Also remember to vote if you enjoyed the guide :D
Bye!~ ^^
JK! here is a list of quick minor information
- True Damage Senna and Prestige Lunar Eclipse Senna both grant a small advanatage: The mists on the ground will drastically change colors when about to expire.
- Always start with Q when hitting towers, you will have more DPS that way.
- When using Q in a tower, try to line up with other teammates to heal them.
- Using Q to pick an out-of-range mist on the ground in bad matchups is worth.
- Allies and enemies can dodge your Q if they're fast enough or if they use a mobility spell.
