Read from Cassiopeia's seat: which stage windows this plan plays for against Swain.
This is Cassiopeia's own plan; across 118 pooled games the lane is Swain-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | At level 1 you both have one ability and no stacking — but his Nevermove (E) root into Vision of Empire (W) is the single combo that can punish you here, so respect his range until your poison engine comes online. |
| Level 2 | Cassiopeia | With Q and Twin Fang online you prime him with Noxious Blast and chain Twin Fang, which refunds most of its cost off the poison — you out-trade his Death's Hand poke. |
| Level 3 | Cassiopeia | A full Q-into-Twin-Fang poison rotation plus your move-speed kiting wins any extended trade he tries to open with his slow, telegraphed Nevermove. |
| Levels 4-5 | Cassiopeia | Ranks in Q and E mean near-continuous Twin Fangs out-DPS his Death's Hand poke, and you sidestep his only setup tool to deny the root every time. |
| Level 6 | Cassiopeia | Petrifying Gaze stuns him out of his Demonic Ascension drain channel if he commits to an all-in — your R turns his attrition fight into your kill window. |
| First item | Cassiopeia | Malignance or early Liandry's plus your passive bonus move speed make you a kiting DPS that pokes him off the wave between his Nevermove cooldowns. |
| Two+ items | Even / skill | He out-scales the teamfight: his AOE Death's Hand, Nevermove pull, and Demonic Ascension drain win grouped 5v5s while you stay squishy — you must close it in the 1v1 before then. |
Level 1 is the real risk: you have one ability and no poison stacking yet, so respect his Death's Hand poke and never stand where his Nevermove (E) can root you into a Vision of Empire (W) bomb — that landed-E window is his only way to blow you up. Once you hit 2-3 and have both Q and Twin Fang, the lane flips: prime him with Noxious Blast (Q), then chain Twin Fang (E) — it refunds most of its cooldown and mana off your own poison, so you out-DPS his Death's Hand poke in any extended trade. Nevermove roots on the return trip, not the throw, so keep moving after the wave passes you and its 12s of downtime is yours.
