How to win lane as Cassiopeia against Yone · 48.36% win rate (1,162 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Miasma is the anti-dash button — ground his engage and the dive kit becomes a farm bot.
Track: Yone's E — Soul Unbound (22–10s cooldown). His burst window — survive it and punish the body he snaps back to.
Read from Cassiopeia's seat: which stage windows this plan plays for against Yone.
This is Cassiopeia's own plan; across 1,162 pooled games the lane is leaning Yone.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Level 1 you have only one ability and no poison to prime, and his Spirit Cleave cone trades evenly with your lone Q. |
| Level 2 | Cassiopeia | At 2 your Q-into-E prime lets Twin Fang hit for real damage, and you can hold Miasma to ground his Q3 dash before he closes. |
| Level 3 | Even / skill | Your full Q-W-E combo and move-speed kiting come online — Miasma grounds the Mortal Steel dash, and Soul Unbound only ever returns him to his body, so he cannot leave your poison. |
| Levels 4-5 | Even / skill | Ranks in Q and E let you chain near-continuous Twin Fang, and any extended trade favours you once Miasma locks his dash down. |
| Level 6 | Even / skill | Petrifying Gaze stuns him before Fate Sealed detonates if he engages facing you, turning a won grounded trade into a kill. |
| First item | Even / skill | Malignance or Liandry's plus your passive AP and move speed make you a dominant lane DPS he cannot poke down or all-in through. |
| Two+ items | Cassiopeia | Two crit items make him a mobile carry that dodges Miasma with double dash plus E body-snap and out-DPSes your squishy, resist-free build. |
Level 1 is even — you have one ability and no poison to prime, and his Spirit Cleave (a frontal cleave, not point-and-click) trades fine into your lone Q. Once you hit 2-3 the lane tilts your way: drop a Q to poison him, E for the empowered Twin Fang, and hold Miasma for the moment he commits the Mortal Steel dash. Grounded mid-dash he is stranded in the cloud, and Serpentine Grace plus the Q speed buff mean he cannot Cleave-and-walk back out. Sidestep the Spirit Cleave cone and never stand in it while you fang him.
