To survive among predators, Kai’Sa became one. Stranded for years with no hope of rescue, Kai’Sa endured through sheer will and a symbiotic second skin adapted from a living Void creature. Now the Daughter of the Void emerges an apex hunter torn between two worlds: the one that birthed her, and the one that made her.

PASSIVE: SECOND SKIN

Caustic Wounds:
Kai’Sa’s basic attacks mark enemies with Plasma, dealing increasing bonus magic damage. After a few successive attacks, the Plasma ruptures for a burst of damage based on the target’s missing health.
Nearby allies’ immobilizing effects add stacks of Plasma.

Living Weapon:
Kai’Sa’s symbiote-suit adapts to her chosen attack style, evolving her abilities based on permanent stats gained from shop items and experience level.

Q: ICATHIAN RAIN

Kai’Sa releases a swarm of missiles evenly distributed among nearby enemies, with additional hits on the same target dealing slightly reduced damage.

Living Weapon:
With enough bonus Attack Damage, Icathian Rain fires significantly more missiles.

W: VOID SEEKER

Kai’Sa fires off a beam of Void energy, revealing the first enemy hit, dealing magic damage, and applying stacks of Plasma.

Living Weapon:
With enough bonus Ability Power, Void Seeker deals more damage and partially refunds the cooldown on champion hit.

E: SUPERCHARGER

Kai’Sa charges up, briefly increasing her movement speed but losing the ability to attack. After charging up, Kai’Sa whips out the big guns to increase her attack speed for a few seconds.
Basic attacks reduce Supercharger’s cooldown.

Living Weapon:
With enough bonus Attack Speed, Supercharger briefly grants true invisibility while charging up.

R: KILLER INSTINCT

Kai’Sa dashes at extremely high speed with long range to a location near an enemy champion marked with Plasma and briefly gains a damage-absorbing shield.
