How to win lane as Master Yi against Heimerdinger · 46.88% win rate over 64 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Heimerdinger | Heimer's Q turrets zone you off the wave from level 1. |
| Level 2 | Heimerdinger | His turret plus Micro-Rocket (W) poke shuts down level 2 completely. |
| Level 3 | Heimerdinger | At level 3 the CH-3X Grenade (E) stun punishes any Alpha Strike dive. |
| Levels 4-5 | Heimerdinger | Levels 4-5 his turret field still out-damages anything you attempt. |
| Level 6 | Heimerdinger | UPGRADE!!! (R) at 6 super-turrets or rocket-waves you off any dive. |
| First item | Heimerdinger | Even at first item his siege and stun keep you behind. |
| Two+ items | Master Yi | Only full crit plus Highlander (R) lets you finally burst through his turrets. |
Heimerdinger hard-counters your early: his H-28G Turrets (Q) zone you off the wave, Micro-Rockets (W) poke you, and any Alpha Strike (Q) engage eats a CH-3X Grenade (E) stun into full turret focus. Don't try to trade — just soak XP and give up some CS.
