What makes Kai'Sa dangerous

Kai'Sa stacks passive plasma that bursts a marked target, and she evolves her abilities based on her items — evolved Q shreds, evolved W is a long-range poke, evolved E gives invisibility and huge attack speed. Her ultimate dashes onto a plasma-marked enemy, letting her dive the backline and clean up fights.

How to counter Kai'Sa

• 1Punish her weak early game — Kai'Sa is item- and level-reliant and does little before her evolves. All-in her lane in the first 10-15 minutes.
• 2Her ult dash needs plasma stacks on the target. Don't let her stack plasma on you, and she can't dive you.
• 3She's melee-range on her carry pattern and squishy. Hard CC and burst catch her when she dives, especially before her E invisibility.
• 4Deny her scaling: end the game before she has three evolves. A behind Kai'Sa never comes online.

What are Kai'Sa's weaknesses?

• ✓Weak, scaling-dependent early game.
• ✓Ult dive needs plasma stacks on the target.
• ✓Squishy diver; hard CC and burst punish her.
• ✓Reliant on items to evolve — deny farm.
