Read from Cassiopeia's seat: which stage windows this plan plays for against Galio.
This is Cassiopeia's own plan; across 129 pooled games the lane is Cassiopeia-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 you have one ability and no poison to feed Twin Fang, so his point-and-click passive auto and Winds of War (Q) poke trade evenly until you land a second spell. |
| Level 2 | Cassiopeia | Your second point across Q/E lets you prime poison and Twin-Fang for damage his slow Q poke and tank base stats cannot answer. |
| Level 3 | Cassiopeia | A full Q-into-E combo with leveled move-speed kiting out-DPSes his early trade, and you can hold Miasma to ground his E dash before he reaches you. |
| Levels 4-5 | Cassiopeia | Ranks in Q and E chain near-continuous Twin Fangs that shred a pre-MR Galio, who has no sustain and no escape from your poison while grounded. |
| Level 6 | Cassiopeia | Petrifying Gaze punishes his Justice Punch dive — but it only stuns a Galio who is facing you, so fire it into his commit and never at a back already turned. |
| First item | Cassiopeia | Malignance or early Liandry's plus your leveled passive move speed make you a kiting poke threat he cannot trade back into before he itemizes MR. |
| Two+ items | Galio | Once he completes Force of Nation / Abyssal his MR blunts your E and poison while his global R and tankiness take over the map — you stay squishy and fall off, so the late game tilts to him. |
Galio is a slow, melee-range AP tank with no early sustain, and you out-poke him from the first level — your Q lays poison, then E (Twin Fang) nukes for bonus damage on a 0.75s cooldown and heals you off it, so you chain it while his Winds of War (Q, 11s at rank 1) and passive auto do far less. Level 1 is roughly even since you only have one ability up and his point-and-click passive auto trades fine, but the moment you have two points across Q/E you prime-and-Twin-Fang for a real lead. Hold W (Miasma) for his Justice Punch — grounded, the dash will not cast at all — and count its own 24s, because that gap is the window he waits for.
