How to win lane as Cassiopeia against Yone · 51.25% win rate over 1,241 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 trades are close since neither champion has a hard engage tool yet, so it comes down to who plays minion positioning better. |
| Level 2 | Even / skill | Level 2 stays even because his Q3 knockup is still on a long cooldown loop and your kit isn't fully online, so poke exchanges roughly cancel out. |
| Level 3 | Cassiopeia | At level 3 your full combo (Q-W-E) outpaces anything he can answer with while dashing through minions, so you start winning trades outright. |
| Levels 4-5 | Cassiopeia | Levels 4-5 extend that lead as your DoT uptime and Miasma zoning make his approach paths actively dangerous for him. |
| Level 6 | Cassiopeia | Level 6 is your biggest spike — Petrifying Gaze punishes any all-in commitment he makes, so you dominate any fight he starts. |
| First item | Cassiopeia | With your first item online your DoT and slow output make it nearly impossible for him to stick on you, keeping the lane firmly in your favor. |
| Two+ items | Yone | Late-game 2+ item teamfights favor him because his ultimate is a flanking tool that lets a fed Yone bypass the frontline and burst you down before you can react. |
Levels 1-2 are close to even — his Q3 knockup threatens a short trade window but he can't commit hard without minion wave support, and your ranged poke keeps him from just walking up freely. By level 3 you have full access to Noxious Blast and Twin Fang, and the moment he tries to dash in through minions to stack Mounting Tempest you can already be chunking his HP from range, forcing him to either eat poke or delay his combo.
