Pros

Heal, Shield and CC in one champion
Good scaling for late game
Many builds for different situations
Higher range in the game (with souls)

Cons

She has to put herself in danger to get souls
Kinda team dependent
Low Mobility
Slow Auto Attack

PASSIVE
ABILITY
ABSORTION (Passive): When units die near Senna, their souls are periodically trapped by the Black Mist. Senna can attack these souls to free them, absorbing the Mist that held them in death and granting Senna 8 gold. Mist fuels her Relic Cannon's power with increased Attack Damage (0.75 attack damage per soul), 20 Attack Range and 8% Critical Strike Chance every 20 stacks.

Q
Piercing Darkness (Q): Senna shoots a bolt of piercing shadow through an ally or enemy. Dealing physical damage to enemies and slowing them by 15% for 1-2 seconds. She and allied champions hit are healed.
W
Last Embrace (W): Senna sends forth the black mist, dealing physical damage to the first enemy hit. After a 1 second delay, or when the unit dies, the target and other nearby enemies are rooted for 1.25-2.25 seconds.
E
Curse Of The Black Mist (E): Senna dissolves into a cloud of mist, becoming a wraith. Allied champions who enter the mist are camouflaged and become wraiths when they leave. Wraiths gain 20% Movement Speed. They are unselectable and hide their identities as long as no enemy champions are nearby.
R
Dawning Shadow (R): Senna fires a blast of light with global range. Enemy champions hit take physical damage. Allied champions hit in a wider area receive a shield for 3 seconds. The shield's power scales with the amount of mist Senna has collected.

This leveling will be your typical skill leveling. You max Piercing Darkness because it's your main damage (besides auto attack), then Last Embrace; its root duration increases, and finally Curse of the Black Mist, because maximizing this ability only gives you more camouflage duration

FLASH

Flash
Always use this spell, it is the most useful for escaping from complicated situations or for engage.

HEAL

Heal
This is my favorite spell when your adc is using another one, if he doesn't want to change his Heal, don't take two, swap to another spell.

IGNITE

Ignite
This spell is very good against teams that have a lot of healing, like Aatrox, Yuumi, Soraka, Samira, etc.

BARRIER

Barrier
It is not one of my favorites, but in some situations it is useful. I recommend to use it against aggressive bot lane, such as Draven, Leona, Alistar, etc.

EXHAUST

Exhaust
For me this is the second best secondary spell you can take, it is very useful against many champions and even more vs. assassins.

Hybrid/Enchanter

Summon Aery gives an extra shield to your allies when hitting them with Piercing Darkness, Dawning Shadow and even Curse of the Black Mist gives them aery shield during the camouflage effect. Really helpful to stack Black Cleaver.


Survivability

Grasp of the Undying provides more scaling for Senna, it will help you at late game to avoid being burst thanks to the permanent heal.


Damage

Fleet Footwork helps you to stay in lane longer without dying thanks to the rune's healing, it also gives you some movement speed which can be useful in some situations.

CORE

Black Cleaver
Probably best item for Senna right now. Good damage for herself and really good for helping her teammates to cause more damage, also providing health for survability and ability haste to spam Q's.
Echoes of Helia
Really good item for dealing more damage in early teamfights, also providing boost to your healing and shielding ( Dawning Shadow and Summon Aery). However, it’s less effective in the mid-late game (around 25 minutes onward), as the additional damage becomes petty. Consider selling it when you reach full build
Moonstone Renewer
One of my favorites. It's great for teamfights and smaller skirmishes with a teammate, offering even more healing, shielding, and additional ability haste to enhance your support capabilities.




SITUATIONAL

Rapid Firecannon
This item has a very good synergy with Senna's passive Absolution, it is useful when you need to out range some abilities like Zenith Blade, Mystic Shot or Alpha Strike, or enemies like Caitlyn.
Phantom Dancer
This item stands out due to its stats, offering three pretty well for Senna, attack speed, critics and ton of movement speed. Go for it for more damage and reduced Piercing Darkness cooldown.
Dawncore
Personally this item feels kinda strange. I would only go for it if my teammates are already dealing significant damage and I've purchased Echoes of Helia and Moonstone Renewer.
Navori Quickblades
This item reduces the cooldown of your abilities when you attack, it is really good to spam Piercing Darkness and Dawning Shadow, also providing some movement speed that suits Senna pretty well.
Blade of the Ruined King
Since you can't build Lord Dominik's Regards due to Black Cleaver, this is your only option against HP stackers such as Cho'Gath.
Chempunk Chainsword
You know, apply grievous wounds; great against healing champions. Chempunk Chainsword gives you AD, ability haste and health
Serpent's Fang
This item is rarely used, but it is very powerful thanks to its shield reduction passive, vs. peel supports such as Lulu, Karma or Renata Glasc is the best you can buy.
Runaan's Hurricane
A solid pick due to its stats. I go for it against melee team compositions, it helps you kill frontline faster thanks to the passive.
Infinity Edge
Risky option due to its cost, but really nice increase in damage, if you feel like the only sourse of damage on your team, or you have a lot of gold, go for it.
Youmuu's Ghostblade
Not really good due to Senna's lethality nerf, but may work against squishy enemies. The active and passive of movement speed provide a decent way of survability.
Edge of Night
This item will help you to avoid cc and not to get picked up. I recommend it against Leona, Nautilus, Morgana and Blitzcrank. But lethality now is not that good for Senna now, there are better options.



BOOTS




Boots of Swiftness
These boots are the best in general, they allow you to kite more easily, counteracting her slow auto attacks

Mercury's Treads
It is a great help in any build, it gives you more magic resistance and tenacity to shorten the duration of cc.

Plated Steelcaps
As Mercury's Treads is a good option in any build, it is very valuable against AD and auto attack compositions.

PASSIVE TIPS & TRICKS


Souls Drop Ratio


This is one of the most important things to know when playing Senna, the soul drop ratio is different for each unit.
  • Epic Monsters (Drakes, Herald and Baron) = 100% ➡ 2 Souls
  • Enemy Kill = 100% ➡ 1 Soul
  • Large Monsters (Red, Blue, Big Wolf, Big Raptor and Big Krug) = 100% ➡ 1 Soul
  • Large Minions (Cannon and Super minion) that Senna doesn't kill = 100% ➡ 1 Soul
  • Small Minions (Melee and Caster) that Senna doesn't kill = 28% ➡ 1 Soul
  • Small Monsters (Small Wolf, Small Raptor and Small Krug) that Senna doesn't kill= 28% ➡ 1 Soul
  • Any Minion and Small Monster that Senna kill = 8.4% ➡ 1 Soul

So... if you are alone in lane and no one can farm the wave you should farm all the minions, unless you have the support item penalty.

MATH EXPLANATION



Q TIPS & TRICKS


Q Range


The range of Piercing Darkness is the same as the range of auto attacks. Buying Rapid Firecannon and having souls increases the range of Piercing Darkness.


Ward + Q (Enemies)


As well as allies, you can throw Piercing Darkness to wards, this is very useful for chasing running enemies.


Ward + Q (Tower)


You can also use ward + Piercing Darkness to throw towers without entering its range.


Ward + Q (Drake)


And to steal drake from outside the pit too.


Vision Plant + Q (Drake)


Also to steal drake you can use the vision plant with Piercing Darkness.


Q Cooldown


For each auto attack that Senna hits, the cooldown of Piercing Darkness is lowered, this is useful if you need to heal an ally quickly because someone applied him Ignite or poison.



W TIPS & TRICKS


Instant Root


Last Embrace takes some time to root, but if it kills an enemy when hit, the root is applied instantly in its area.


W + Flash


You can extend the range of Last Embrace by using Flash at the same time as this ability



E TIPS & TRICKS


E Entry


Although it may not seem like it, Curse of the Black Mist is a great way to enter places like the drake or to gank. Enemies think it's only Senna, but there are 4 more champions in there.


Video from Senna's Champion Spotlight (I have no friends to record it)


R TIPS & TRICKS


R to objetives


You can't steal objectives with Dawning Shadow (please don't do this, I've seen many senna doing this).


R to souls


With the R you can grab the souls from the floor. This is not useful but I think it's important to know to learn the 100% of the champion.

I hope this guide has helped you to improve your Senna game. All comments and suggestions are accepted as long as they are respectful.
