How to win lane as Karma against Heimerdinger · 46.47% win rate (510 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Poke war on your terms — RQ out-trades any single spell, and your shield erases his answer.
Track: Heimerdinger's E — CH-2 Electron Storm Grenade (11s cooldown). The stun makes his turret nest lethal — dodge it before diving.
Read from Karma's seat: which stage windows this plan plays for against Heimerdinger.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Karma has Mantra from level 1, so your Mantra-Q opener is real chip in the one window before any turret exists — genuinely a skill matchup. |
| Level 2 | Heimerdinger | He plants his second H-28G turret and parks the wave behind it, so your Q now trades into beams plus W rockets and the math flips to him. |
| Level 3 | Heimerdinger | Three turrets plus 1325-range Micro-Rockets zone you off the minions — your 950 Q means nothing against hardware that shoots for free. |
| Levels 4-5 | Heimerdinger | Layered turret beams plus W poke out-chip your Q rotations and your Inspire shield can't outlast a grid that fires on every step you take. |
| Level 6 | Even / skill | Karma gets no new ult at 6 while his UPGRADE!!! is a real spike, so the window comes down to whether you dodge the empowered grenade and land RW — a true coin-flip. |
| First item | Heimerdinger | Liandry's and turret haste out-burn your first item while 1325-range rockets keep you out — your shield melts before you reach him. |
| Two+ items | Heimerdinger | He out-scales the lane completely — the haste-boosted grid plus W rockets kite your thin frame and Karma has no late item spike to answer it. |
Heimer hands you exactly one clean window: level 1, before any turret is planted, where you open RQ Soulflare — Karma has Mantra from level 1, so the delayed-zone is real chip — and contest the wave on even footing. From level 2 he plants his second then third H-28G turret, the minions park behind the grid, and now your Inner Flame poke is answered by multiple beams plus his W Hextech Micro-Rockets — your trade math goes negative every time you step up. Don't walk into the grid to throw a Q he just out-DPSes; last-hit at max Q range, hold mana for one W tether attempt, and respect his E grenade stun.
