How to win lane as Cassiopeia against Quinn · 55% win rate over 60 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Quinn | Level 1 he just needs to poke — Vault knockback and Harrier-charged autos chip you while you sit on one ability with no Q poison economy to punish back. |
| Level 2 | Even / skill | Around level 2-3 you can prime-and-Twin-Fang, but his ranged poke and burst still trade roughly even until your poison and refunds fully ramp. |
| Level 3 | Cassiopeia | Full Q-into-E online: Twin Fang costs almost nothing into a Q-poisoned target, so your continuous DoT-fed chain out-grinds his single bursts of Harrier poke. |
| Levels 4-5 | Cassiopeia | W Miasma grounds his Vault — pre-placed on his escape path it strips the dash recast that defines his kite, and Twin Fang shreds him while he's stuck. |
| Level 6 | Cassiopeia | Petrifying Gaze ends his all-in: he Vaults or steps to auto facing you, you R the cone for the stun and Twin-Fang the duration into a kill he can't disengage. |
| First item | Cassiopeia | Liandry's or Malignance plus your no-boots passive move speed lets you chase through Harrier kiting and turn poison ticks into a closing kill threat. |
| Two+ items | Even / skill | A two-item Quinn reclaims it — she kites outside your Q range and bursts you with Harrier autos while you stay squishy, so end the lane before that spike. |
Level 1 is his — you have one ability and no poison economy, so his Vault knockback plus a couple of Harrier-charged autos chip you for free before Twin Fang is online. Don't throw a naked Q he just nimble-kites; last-hit with the edge of Q and accept a little poke. By 2-3 the math flips: once a Q-poisoned target refunds your Twin Fang cooldown, your continuous chain DPS beats his single-burst poke, and you never need to chase — let him walk into the poisoned wave.
