How to win lane as Heimerdinger against Olaf · 51.82% win rate (467 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Axes clear turrets and his sustain out-grinds your poke — but pre-6 he can't actually reach you through the slow field. Post-6 Ragnarok walks through the whole setup: rebuild deeper each level.
Track: Olaf's R — Ragnarok (100–80s cooldown). CC-immune — your stun won’t hold him.
Read from Heimerdinger's seat: which stage windows this plan plays for against Olaf.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Olaf | You have only one turret and no grenade yet, so Olaf's Undertow (Q) slow into Reckless Swing (E) true damage can shove you off the wave before your nest exists. |
| Level 2 | Even / skill | Your second turret and slowing beams come online, but Tough It Out (W) shields the chip and his axe-reset Q still lets him trade back, genuinely even until the grenade lands. |
| Level 3 | Heimerdinger | With the CH-3X Lightning Grenade (E) up, any walk-in eats a center-stun plus turret beams, and he can't grab an axe to reset Q while frozen in the nest. |
| Levels 4-5 | Heimerdinger | Three turret charges plus the stun grenade make this your peak: a full nest deletes any all-in before the Tough It Out shield matters. |
| Level 6 | Heimerdinger | UPGRADE!!! (R) gives you a wider, longer-stunning grenade to lock him the instant Ragnarok's CC-immunity drops, then the turrets finish. |
| First item | Heimerdinger | Your super-turret and siege architecture keep zoning a dash-less, range-less Olaf who still has no way into the nest without eating the grenade. |
| Two+ items | Heimerdinger | He must enter melee range to do anything, and your turret nest plus stun deny that commit before his Reckless Swing true-damage scaling matters. |
Olaf's only real shot is the Level 1 contact window: you have one turret and no stun, so respect his Undertow (Q) axe slow into Reckless Swing (E) true damage, and don't get pinned against the wave while he picks axes back up to reset Q. The instant you hit Levels 2-3 you flip it: a second turret plus the slowing beams turn the lane into a zone, and once the CH-3X grenade (E) is up at 4-5 he can't walk in without eating a center-stun. Last-hit behind the nest and deny him axe pickups so his Q slow never chains.
