How to play as Kai'Sa
- Stack plasma with autos then dump Q (Icathian Rain) for burst
- R (Killer Instinct) to a nearby ally — gap close + shield = safe engage
- E (Supercharge) to escape or chase — invisibility + attack speed
- Build Kraken Slayer + Manamune + Nashor's Tooth for hybrid burst
- Passive shreds armor based on evolved abilities — itemize AP + AS early
- Lane: long-range W (Void Seeker) poke to set up plasma
How to beat Kai'Sa
- Burst her before R (Killer Instinct) — it ports to an ally with a shield
- Passive (Second Skin) — autos stack plasma, 4-5 stacks = true damage pop
- Buy Mercury's Treads + Banshee's Veil to soak her burst
- Hard CC champs (Leona, Morgana) shut her down
- Punish her E (Supercharge) windows — she goes invisible + attack speed
- Kill her before she finishes Manamune + Nashor's Tooth
Abilities
Second Skin
Innate - Living Weapon: Kai'Sa can evolve each of her basic abilities by obtaining a finished item. Evolving an ability causes her to enter a 2-second cast time. The upgrade is lost if the item is sold.
Innate - Caustic Wounds: Kai'Sa's basic attacks on-hit and Void Seeker inflict stacks of Plasma to enemies for 4 seconds, refreshing on subsequent hits and stacking up to 5 times. Her and nearby allies' immobilize effects and polymorph against enemy champions will also apply a stack of Plasma.
Plasma stacks inflicted by Kai'Sa will deal 5 to 12 for 15% (+ 15% AP) bonus magic damage. The fifth stack consumes them all to deal additional bonus magic damage equal to 15% (+ 2.5% per 100 AP) target's missing health, capped at 400 against monsters.
Icathian Rain
Active: Kai'Sa shoots a swarm of 6 missiles that evenly distributes among nearby sight enemies, each one hitting their target after 0.4 seconds to deal physical damage. Minions below 35% health take 150% damage. Monsters take 50% damage. Non-minions take % damage from missiles beyond their first.
Second Skin Bonus: Icathian Rain instead fires 12 missiles.
A nearby enemy is required to cast this ability.
Void Seeker
Active: Kai'Sa shoots a void bolt in the target direction that deals magic damage to the first enemy hit, inflicts 2 Plasma, and true sight them for 4 seconds.
Second Skin Bonus: Void Seeker inflicts 3 Plasma instead. If it hits an enemy champion, the cooldown is reduced by 70% total cooldown.
Supercharge
Active: Kai'Sa charges up over the cast time, during which she is still allowed to move and gains bonus movement speed, increased by type= bonus attack speed%. Afterwards, she gains bonus attack speed for 4 seconds.
Supercharge's remaining cooldown is reduced by 0.5 seconds on-attack.
Second Skin Bonus: During the charge, Kai'Sa turns invisibility for 0.7 seconds.
Killer Instinct
Active: Kai'Sa shields herself for 2 seconds and dashes to a target location near a sight enemy champion that was affected by Plasma within the last 4 seconds. The shield's duration is then refreshed.
An enemy champion within range affected by Plasma is required to cast this ability. Killer Instinct Basic attack reset Kai'Sa's basic attack timer. Kai'Sa can cast abilities during the dash.
