Read from Cassiopeia's seat: which stage windows this plan plays for against Warwick.
This is Cassiopeia's own plan; across 210 pooled games the lane is leaning Warwick.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Warwick | You have one ability and no poison stacked while his Jaws of the Beast drain already heals through your chip — last-hit at Q range and don't throw a lone Q he can walk through to trade back on you. |
| Level 2 | Even / skill | With Q+E online you prime poison and chain Twin Fang when he steps to farm, but his drain heals most of it back — level 2 turns on whether he lands Jaws of the Beast. |
| Level 3 | Warwick | Your Serpentine Grace move speed and full Q-to-E combo kite him, but Miasma only grounds Jaws of the Beast this early and his drain still heals through the poison — level 3 stays his. |
| Levels 4-5 | Cassiopeia | Ranks in Q and E let you chain near-continuous Twin Fang — grounded, Warwick loses both Jaws of the Beast and Infinite Duress, and every extended trade with them. |
| Level 6 | Cassiopeia | Petrifying Gaze cancels Infinite Duress if you stun him as he leaps in — face the dash and pre-empt it before the suppress locks you, then Twin Fang him down instead of letting the channel heal him. |
| First item | Cassiopeia | Malignance or early Liandry's plus boots-free Serpentine Grace move speed make you a kiting DPS nightmare — your ramping poison out-damages his Blood Hunt drain heals. |
| Two+ items | Cassiopeia | You stay ahead in the straight duel — Miasma grounds his R leap, Petrifying Gaze cancels it on the dash, and your poison out-races his sustain; only a fog-flank Duress that locks you first flips it. |
Warwick wants a sustained fight and you are built to win exactly that — but level 1 you have only one ability and no poison stacking, so don't throw a lone Q he can walk through and then auto you while Blood Hunt isn't even online yet. From level 2 prime with Noxious Blast (Q) and immediately Twin Fang (E) — the refunded cooldown off the poison lets you fire E again almost instantly, and his passive heal only ramps on low targets, so as long as you stay healthy your DPS out-paces his sustain. Save Miasma (W) for the moment he commits — it grounds his Infinite Duress leap and the slow keeps him parked in your poison.

Cassiopeia takes Conqueror on the Precision tree with Presence of Mind, Legend: Haste and Last Stand, and Sorcery secondary (Manaflow Band and Transcendence) vs Warwick.
Start Doran's Ring + 2 Health Potions and back for Oblivion Orb (≈800g) — cuts his healing. Build Seraph's Embrace / Liandry's Torment first, then Rylai's Crystal Scepter, with No boots — Serpentine Grace scales with level.
