Abilities

P
Second Skin
Innate - Living Weapon
Kai'Sa can evolve each of her basic abilities 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.
Basic attacks each apply 1 stack and Void Seeker applies 2 stacks, increased to 3 if it is evolved.
Her and nearby allies' immobilizing effects and polymorphs against enemy champions will also apply a stack of Plasma.
Innate - Caustic Wounds
Plasma stacks applied by Kai'Sa's basic attacks or Void Seeker deal (12% AP) additional magic damage plus (3% AP) additional magic damage per Plasma stack before application, up to a total of (24% AP) additional magic damage at 4 Plasma stacks before application.
The fifth stack against a target consumes them all to deal additional magic damage equal to 15% (6% per 100 AP) of the target's missing health, capped at 400 against monsters.
