How to win lane as Olaf against Mordekaiser · 55.91% win rate over 2,200 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Olaf | Morde is a feeble level-1 and your Q-slow-into-auto plus health-scaling passive win first contact outright. |
| Level 2 | Mordekaiser | His R is down but at 2 he can land E-pull into an isolated Q-slam plus W shield to flip a sloppy trade — respect the level-2 spike. |
| Level 3 | Olaf | Your Q-stick into guaranteed E true damage chunks him before his W shield matters — your hardest punish window. |
| Levels 4-5 | Olaf | Axe-reset perma-slows deny his isolated Q while W omnivamp out-sustains his Q-and-W chip in short trades. |
| Level 6 | Mordekaiser | His R Realm of Death drags you into a 1v1 and steals your stats — Ragnarok can't cleanse the zone, so this is his swing. |
| First item | Olaf | Your Black Cleaver / bruiser spike with axe slows and W sustain out-grinds his shield-heal — force every all-in here. |
| Two+ items | Olaf | On his R cooldown your flat true damage and relentless slows still beat him 1v1 — close it before full build. |
Morde is one of the weakest level-1s and so is the trade math for him here — at Level 1 land your Q to slow him, walk up an auto, and your passive attack speed ramps as you take his return. Levels 2-3 are your peak: throw Q to stick him, then E for a guaranteed true-damage chunk he simply can't shield through yet, and pick the axe back up to refund the cooldown so you can perma-slow him out of his own Q-slam range. Dodge his E pull — if he yanks you and lands an isolated Q, that empowered slam plus W shield flips the trade.
