How to win lane as Kai'Sa against Sivir · 49.62% win rate over 8,674 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sivir | Sivir's level 1 Boomerang and W push and out-poke your weak early Kai'Sa. |
| Level 2 | Sivir | At level 2 Sivir's W bounce plus Q keeps the poke and wave lead against you. |
| Level 3 | Sivir | Level 3 still favors Sivir as Spell Shield blanks your Q and her Q out-trades. |
| Levels 4-5 | Even / skill | Levels 4-5 even out as your Q max lets you contest short trades on her cooldowns. |
| Level 6 | Even / skill | Level 6 is a skill fight since her R kite counters your dash while your E threatens re-engage. |
| First item | Kai'Sa | Your first item and Plasma stacks let you out-DPS Sivir's raw AD. |
| Two+ items | Kai'Sa | With 2+ items your dash resets and burst delete Sivir before her team speed-buff matters. |
Sivir owns levels 1-3: her Boomerang (Q) plus W bounce out-trades and out-pushes you, and her Spell Shield (E) blanks your Q poke, so respect the wave and last-hit safely rather than walk into her double-poke.
