How to win lane as Heimerdinger against Karma · 53.53% win rate (510 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Weather the poke — nest up and stun her Focused Resolve dive.
Track: Karma's W — Focused Resolve (12s cooldown). Her root tether — breaks if you LoS / outrange it.
Read from Heimerdinger's seat: which stage windows this plan plays for against Karma.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Karma's Q reaches you while your nest is still a single turret, so the Level 1 exchange is a straight poke trade — deny her last hits and don't over-step. |
| Level 2 | Heimerdinger | Your second turret plus the slowing electron beam wall off her CS, and with no dash she can't farm without walking into beam-and-turret range. |
| Level 3 | Heimerdinger | Three banked turret charges turn her CS line into a tax booth she can't escape, since Karma has no mobility to dodge the beams. |
| Levels 4-5 | Heimerdinger | The CH-3X center-stun plus W-rockets and turret fire is burst her E shield can't fully absorb — bait the shield, then commit the stun. |
| Level 6 | Even / skill | Mantra has been available since level 1, so nothing new lands for her at 6 — your UPGRADE!!! against her 40s Mantra-W root read is a genuine coin-flip. |
| First item | Heimerdinger | A UPGRADE!!! super-turret and full three-charge nest out-zone and out-siege an enchanter who can only poke and shield from range. |
| Two+ items | Heimerdinger | You still win the siege and the freeze, but cash the lead before her Mantra shields and speed-ups turn a teamfight in her carries' favor. |
Karma's Q is the only thing that touches you at Level 1, so soak a little poke but don't over-extend before your nest exists. From Level 2 you plant a second H-28G turret and the slowing electron beam starts owning her CS line — she physically can't last-hit comfortably without stepping into beam-and-turret range, and with no dash she can't dodge them. Keep banking turret charges, trade your Q-beam poke for her Q poke, and don't blow your single CH-3X grenade chasing a shield.
