How to win lane as Quinn against Cassiopeia · 55.49% win rate over 173 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Quinn | Pre-Q Cassiopeia is helpless — you out-range her and Harrier auto-resets let you leap-trade and E out before her poison exists. |
| Level 2 | Even / skill | Her level 2 adds Miasma's ground but your kite and range still roughly trade even before her DPS fully ramps. |
| Level 3 | Cassiopeia | Twin Fang melts you on poisoned targets and your Q blind only kills autos she barely uses — her sustained DPS takes over. |
| Levels 4-5 | Cassiopeia | She grounds your Vault with W and out-sustains your poke with her passive move speed and ramping poison. |
| Level 6 | Cassiopeia | Her R face-stun locks you in melee where Twin Fang bursts you — your R is roam-only and can't answer her combat ult. |
| First item | Cassiopeia | Her Liandry's/Lich Bane spike out-DPSes your lethality through the blind, so straight trades favor her now. |
| Two+ items | Even / skill | Late, you're a squishy picker and she's a scaler — even, because your roam/pick value offsets her duel dominance only if you snowballed. |
Levels 1-2 are yours — pre-Q Cassiopeia has no reliable poke and you out-range her with autos, so abuse Harrier: leap in on the Vulnerable proc, then E-Vault back out before she can land Noxious Blast (Q). Bait her Q poison and sidestep it; uncharged she can't sustain her HP through your trades. Stay mobile because once she has W-Miasma at level 3 she'll ground your Vault and your kite turns off.
