How to win lane as Cassiopeia against Master Yi · 43.8% win rate over 121 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Cassiopeia owns level 1 — your Q out-pokes a melee Yi who has no way to answer at range. |
| Level 2 | Cassiopeia | Level 2 stays yours: the W slow-zone denies his engage entirely, so he can't even start the trade he wants. |
| Level 3 | Cassiopeia | Level 3 is yours — E poison-heal spam chunks him down while sustaining you through his scratch damage. |
| Levels 4-5 | Even / skill | By 4 his Wuju Style points bring the lane to even — trades are honest now, so lean on spacing, not stats. |
| Level 6 | Master Yi | Master Yi takes level 6: Highlander and the Q dash dodge your damage patterns and tilt fights his way. Save Gaze for his commit, not for poke. |
| First item | Master Yi | First item is his — Wuju true damage out-DPSes you the moment he sticks. Ground him, stun him, or be somewhere else. |
| Two+ items | Cassiopeia | Late is Cassiopeia's: R's AoE stun and your zone control lock him down before the resets start, and a locked-down Yi melts in seconds. |
Bully him hard. Your Q out-pokes his melee frame at 1, the W slow-zone denies his level 2 engage outright, and from 3 the E poison-heal loop chunks him while healing back his scratch damage. Zone him off CS, stack your lead, and force him to farm under tower where your Q lands free.
