How to win lane as Jax against Heimerdinger · 49.48% win rate (291 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Counter Strike dodges turret autos — the nest that bullies every other melee just feeds your E. Q onto the inventor, stun the trio, kill from there.
Track: Heimerdinger's E — CH-2 Electron Storm Grenade (11s cooldown). His self-peel stun. Dodge it.
Read from Jax's seat: which stage windows this plan plays for against Heimerdinger.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is skill-dependent: with one turret and no grenade, your Counter Strike beam-dodge plus a leash-leap can win the first contact, but he can still poke with beams and a rocket, so it's a coinflip on the leash and your angle, not a free win. |
| Level 2 | Heimerdinger | By level 2 his second H-28G turret taxes every CS, and your Q-W walks into beam range with no Counter Strike payoff against his spells — the lane swings his way. |
| Level 3 | Heimerdinger | At level 3 his turret nest plus a banked CH-2 grenade zone your Leap Strike, and the stun lands through Counter Strike since E only dodges basic attacks, not the grenade. |
| Levels 4-5 | Heimerdinger | Levels 4-5 are his strongest window: two turrets plus the center-stun grenade mean any jump-in gets locked and beam-volleyed while Counter Strike can only blank the autos, not the stun. |
| Level 6 | Even / skill | Your level 6 Grandmaster-at-Arms gives the burst Armor/MR to trade, but UPGRADE!!! turns his next grenade bigger with a wider stun footprint, so the all-in stays a coinflip — hold it until items. |
| First item | Jax | Trinity Force or BotRK lands and your Q-W landing hit plus stacking on-hit out-DPS his whole turret nest in a committed all-in, and Leap Strike sticks through his kite — the lane tips to you here. |
| Two+ items | Jax | At 2+ items Grandmaster-at-Arms' resists plus Sterak's let you tank the entire nest and one-shot the dash-less yordle, so the side-lane duel is firmly yours. |
"Level 1 is a genuine coinflip, not a free win: with only one turret up and no grenade banked, your Counter Strike (which dodges his turret beams and his autos) plus a leash-assisted Leap Strike CAN win the first contact — but he can still chunk you with turret beams and a W rocket while you walk up, so only commit if the leash and angle are clean. By levels 2-3 he stabilizes hard: a second H-28G turret taxes every CS you try to take, and your Q-W gap-close walks straight into beam range. Remember Counter Strike only blanks basic attacks, so it eats his turret beams and his autos but does NOT dodge the W Micro-Rockets' impact, and it never dodges the E grenade or its stun. Don't burn E on the approach — hold the recast stun for the exact moment you land your leap."
