Playing against Kaisa

How to counter and exploit weaknesses

1

Stay with your minions: her Q spreads missiles among all targets. Isolated, you take all the missiles.

2

Her R can only target enemies marked by passive or W — if she doesn't hit you, she can't R onto you.

3

Kai'Sa has relatively short range (525) and is weak early — punish her with longer-range ADCs.

4

Her W (Void Seeker) applies 2 passive stacks and marks for R: dodge it as priority in mid/late game.
