Kai'Sa

Second Skin 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 4 − 24 (based on level) (+ 1 : 6 (based on level) per Plasma stack before application) (+ 12% : 24% (based on Plasma stacks before application) AP) bonus magic damage. The fifth stack against a target consumes them all to deal additional bonus magic damage equal to 15% (+ 6% per 100 AP) of the target's missing health, capped at 400 against monsters.

Playing the matchup

Playing as Kai'Sa

  • Try to catch enemy carries alone to burst them with Icathian Rain.
  • Work with your teammates to set up your Ultimate and optimize damage with your passive.
  • Make sure to buy items that will evolve at least 1 or 2 of your spells.

Playing against Kai'Sa

  • Kai'Sa is very good at picking off isolated enemies. Stick together against her.
  • Kai'Sa is very vulnerable to getting outranged by mages and long range carries.
  • Make sure to place wards in your blind spots so you can see Kai'Sa coming.

Lore

Claimed by the Void when she was only a child, Kai'Sa managed to survive through sheer tenacity and strength of will. Her experiences have made her a deadly hunter and, to some, the harbinger of a future they would rather not live to see. Having entered into an uneasy symbiosis with a living Void carapace, the time will soon come when she must decide whether to forgive those mortals who would call her a monster, and defeat the coming darkness together… or simply to forget, as the Void consumes the world that left her behind.
