Read from Yone's seat: which stage windows this plan plays for against Cassiopeia.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | At level 1 the lane is even before her zone control exists, a pure skill start. |
| Level 2 | Even / skill | Level 2 stays a skill matchup while she's still mana-constrained and immobile. |
| Level 3 | Cassiopeia | Her level 3 Miasma grounds your dash and tilts the lane to Cassiopeia. |
| Levels 4-5 | Cassiopeia | Through 4-5 her Twin Fang DPS and ground zone keep her firmly ahead. |
| Level 6 | Cassiopeia | Petrifying Gaze at 6 punishes your all-in, so level 6 favors Cassiopeia. |
| First item | Cassiopeia | Her first-item DPS spike outpaces you, keeping the mid-game hers. |
| Two+ items | Yone | With crit and armor pen late you finally outscale her, flipping to Yone. |
At levels 1-2 the lane is even skill matchup; Cassiopeia is mana-starved and immobile, so you can Q-poke and contest farm before her ground zone comes online. Track Miasma: 24s at rank 1, 16s at rank 5 — inside the cloud you are grounded and your Q3 dash will not fire. Step in once it is spent. Once Cassiopeia has her Miasma pool down she zones your E-in path and grounds you so you can't dash out; if you commit into her Twin Fang spam without dodging Q, she chunks you and kites away.
