Kai'Sa vs Sivir

Confidence mediumUpdated Jun 7, 2026

Overview

Kai'Sa must manage (E) to create all-in windows after support CC or item spikes.
The lane turns on wave state: thin waves let (Q) isolate Sivir, enabling burst trades.
Kai'Sa wins short trades with setup and scales better into mixed damage and repositioning.

Trading pattern

Step forward to auto or (W) when Sivir walks up for CS if support threat is low.
Avoid committing trades when (E) is available to block your (W).
Use thinned waves to maximize (Q) damage on Sivir instead of minions for burst trades.

Danger windows

(E) blocks your (W) and negates your all-in setup; avoid trading when it's up.
Enemy support in aggressive position or brush control can punish your step forward for last-hit trades.
Avoid using (E) forward before enemy engage or poke cooldowns are spent to prevent overextension.

Early game

Use the first three waves to farm safely and thin the wave for isolated (Q) damage.
Avoid using (E) forward before enemy engage or poke cooldowns are spent.
Punish Sivir's last-hit attempts only if enemy support cannot immediately trade back or zone.

Power spikes

First completed item unlocks evolves, increasing (Q) damage and all-in threat; seek support CC to commit.
Level 6 (R) allows repositioning onto marked targets, turning small CC into kills; use only with setup.
Evolve thresholds improve damage and mobility, enabling safer trades and better chase potential.

Win conditions

Convert isolated damage and support CC into kills after item spikes to force Sivir off wave.
Use lane pressure and health leads to crash waves, deny plates, and set up dragon control.
Scale into teamfights where (R) allows repositioning for burst DPS on marked targets behind enemy lines.
