How to win lane as Kai'Sa against Heimerdinger · 49.88% win rate over 2,167 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is even because neither of you commits before the first turret or your abilities are online. |
| Level 2 | Heimerdinger | Level 2 favors Heimerdinger since his W beam and first turret out-poke your bare step-up. |
| Level 3 | Kai'Sa | Level 3 is yours: full QWE lets you dodge a beam and burst a lone Heimer if a turret is down. |
| Levels 4-5 | Heimerdinger | Levels 4-5 swing to Heimerdinger as stacked turrets zone the corridor you must farm in. |
| Level 6 | Heimerdinger | Level 6 is his: the upgraded turret or grenade ult outranges your all-in through the turret field. |
| First item | Heimerdinger | At first item he still zones your CS corridor and soaks your Q with turrets, keeping the edge. |
| Two+ items | Kai'Sa | By 2+ items your evolved passive and R flank finally out-mobility his static zone and the lane flips to you. |
At level 1-2 it's about respecting turret placement; his level 2 W and first turret already out-poke your step-up, so trade only when a turret is on cooldown.
