How to win lane as Cassiopeia against Yasuo · 49.52% win rate (525 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Wind Wall blocks Q and E both, but Miasma grounds his dashes — an honest fight between his wall cooldown and your zone.
Track: Yasuo's W — Wind Wall (25–17s cooldown). Blocks every projectile for its duration — hold your poke until it is spent.
Read from Cassiopeia's seat: which stage windows this plan plays for against Yasuo.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 you both lack tools — one ability, no poison stacking, and his Q out-pokes your single Noxious Blast, so it's an even farm phase. |
| Level 2 | Cassiopeia | At 2 your Q-into-Twin-Fang trade beats his Steel Tempest poke on poisoned-target damage, but Wind Wall blocks the fangs — only the placed Noxious Blast zone goes through it. |
| Level 3 | Cassiopeia | Miasma grounds his E and your full Q-E poison out-DPSes him — he can't dash in or out of the cloud to escape the ticks. |
| Levels 4-5 | Cassiopeia | Ranks in Q and E let you chain near-continuous Twin Fangs while Miasma cancels every dash, so you win all extended trades. |
| Level 6 | Cassiopeia | Petrifying Gaze stuns him out of his all-in or mid-E before he has any crit, converting your poke lead into a kill. |
| First item | Cassiopeia | Your first-item poison DPS plus passive move speed dominate lane — you kite his dashes and his single IE component can't crit-trade with your sustained ticks yet. |
| Two+ items | Yasuo | Yasuo out-scales hard: IE plus passive double-crit autos and knockup-into-R run you down while you stay squishy and short-ranged. |
Level 1 is a coinflip — one ability, no poison to stack, and Steel Tempest out-pokes a single Noxious Blast, so farm safely. From 2 with Q+E, start priming: land Noxious Blast, then Twin Fang for the poisoned-target bonus and the refund. Know the wall — Noxious Blast is a placed ground zone and passes it, but Twin Fang is a projectile and Wind Wall eats it, so poke with Q while the wall is up and save the fangs for after it drops. At 3, drop Miasma as he winds up Sweeping Blade; grounded, the dash dies and he stands in the poison.
