Senna's abilities
Passive, spells and ultimate
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. Mist fuels her Relic Cannon's power with increased Attack Damage, Attack Range, and Critical Strike Chance. Attacks from Senna's Relic Cannon take longer to fire, deal bonus damage, and briefly grant her a portion of her target's Move Speed.

Playing as Kai'Sa
Tips to maximize your impact
- Use Q on an isolated target
Cast Icathian Rain (Q) on an isolated target: the missiles split between nearby enemies, so a lone target takes them all.
- Attack after your ally's CC
Attack right after your support lands CC: with Second Skin (passive), your allies' immobilizing effects also stack Plasma.
- Mark your target before your R
Before Killer Instinct (R), stack Plasma on your target, from range with Void Seeker (W): the dash needs a marked target and gives you a shield.
- Play around your evolves
Make use of each spell that Second Skin (passive) evolves: Supercharge (E) makes you invisible to get in, and Icathian Rain (Q) fires more missiles at a lone target.
Playing against Senna
How to counter and exploit weaknesses
- Punish her when she goes for a soul
Take a trade when she steps up for a soul: each bit of Mist she absorbs with Absolution (passive) gives her AD, attack range and crit.
- Spread out if her embrace hits you
If Last Embrace (W) hits you, move away from your allies: after a short delay, you and nearby allies are rooted.
- Target her when she steps up
If you can engage, target her when she steps up for Piercing Darkness (Q): she has no dash to get away.
- Beware the wraiths
Back off when her team disappears into Curse of the Black Mist (E): her allies are camouflaged there, then fast and unselectable.
