Innate - Living Weapon: Kai'Sa can evolve each of her ability by gaining a set amount of permanent stats from items and stat growth, granting them additional effects. Evolving an ability causes her to enter a 2-second cast time. The upgrade is lost if the stat requirement is no longer met.

Innate - Plasma: Kai'Sa's basic attacks on-hit and Void Seeker apply stacks of Plasma to enemies for 4 seconds, refreshing on subsequent applications and stacking up to 5 times.
