How to win lane as Kassadin against Heimerdinger · 45.45% win rate over 11 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | You're both weak at level 1 — he has only one turret and you have only Null Sphere, so neither can commit and it's a coinflip wash. |
| Level 2 | Heimerdinger | His second H-28G turret plus a Micro-Rocket volley out-trades your single mana-hungry Q before you have Nether Blade for sustain. |
| Level 3 | Heimerdinger | Three turret beams crossfire the wave and zone you off CS while your short-range Q can't poke back through them. |
| Levels 4-5 | Heimerdinger | Without Nether Blade mana back you can't contest his turret nest, and the CH-2 grenade catches you with no blink to escape yet. |
| Level 6 | Heimerdinger | Riftwalk lets you dodge the grenade at 6, but it's a flee button here — you still can't out-DPS three turrets to kill him. |
| First item | Heimerdinger | His turret zone is fully scaled while your Rod of Ages stall only buys farm, so he keeps the lane lead into the first item. |
| Two+ items | Kassadin | With Riftwalk stacked and Nashor's/Lich Bane online you blink through the turrets and one-combo an immobile Heimer who can't reposition. |
Heimer's turrets are the whole problem — the H-28G nest zones the wave so hard that your single Null Sphere can't reach a last-hit without standing in turret beams plus a Micro-Rocket. Don't try to trade: you have no Nether Blade mana back yet and your Q is mana-hungry and short-ranged. Hold the Null Sphere shield to eat the CH-2 grenade stun rather than burning it on poke, because if his E lands you take a full rocket-plus-turret-crossfire combo with no blink to escape until 6. Concede the wave, last-hit what you safely can under tower, and accept you're losing this stage.
