How to win lane as Olaf against Cassiopeia · 56.1% win rate (656 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
She kites you out — survive, then stick with axes and run her down — her Miasma can’t stop Ragnarok.
Track: Cassiopeia's W — Miasma (24–16s cooldown). Grounds you — dashes and movement abilities are disabled inside it.
Read from Olaf's seat: which stage windows this plan plays for against Cassiopeia.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Olaf | She is a bottom-tier level-1 and you are top-tier — Undertow slow into a passive-fueled auto wins first contact before she has a single poison stack. |
| Level 2 | Even / skill | Her Q poke starts to sting once she has stacks, but a committed Q-slow trade still out-damages it — genuinely even as she finds range. |
| Level 3 | Cassiopeia | With W grounding online she cancels your gap-close and kites your axe to poison range — she edges this window before your 6 spike. |
| Levels 4-5 | Even / skill | You out-trade a pre-item Cassiopeia in short bursts, but her grounding plus your dependence on Ragnarok being up keeps it skill-tested. |
| Level 6 | Even / skill | Ragnarok ignores her R stun but not her W slow, so you can dive — a clean flash-R or a well-placed Miasma still denies it. Read-dependent. |
| First item | Even / skill | Your Black Cleaver / Bramble all-in is oppressive with perma-slows, yet her first poison item lets her trade poke for your true damage — a coin-flip on positioning. |
| Two+ items | Even / skill | Liandry's and Rylai's let her perma-slow and out-DPS your flat true damage — but if you snowballed she can still be too far behind to kite you, so it stays skill. |
Cassiopeia is one of the worst level-1 champions in the game and you are one of the best, so step up immediately — throw Undertow on the wave to land a slow, then walk in for a Q-slowed auto while your passive attack speed climbs. She has no poke that out-damages a committed melee trade this early, and no escape: her W grounding and R stun don't exist yet. Don't over-extend past river on her poison stacks alone, but every time she steps to last-hit, axe-slow her and punish.
