Read from Galio's seat: which stage windows this plan plays for against Cassiopeia.
This is Galio's own plan; across 129 pooled games the lane is Cassiopeia-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is an even mana-and-CS standoff — you have only Winds of War and no engage, but Cassiopeia can't commit either with just Noxious Blast. |
| Level 2 | Even / skill | By 2-3 her Twin Fang and poison ramp out-trade you from outside Justice Punch range — but Miasma is 24s, and once it is spent the level is yours. |
| Level 3 | Even / skill | With Q-W-E up you can all-in, but Miasma grounds the dash outright, so the level turns on one bait: her cloud, or your Shield of Durand channel. |
| Levels 4-5 | Even / skill | Twin Fang is a 0.75s cooldown that heals her, so long trades favour her while short W-taunt bursts still trade back evenly. |
| Level 6 | Even / skill | Hero's Entrance is your level-6 answer — you never have to out-poke a 3.5s Noxious Blast, you leave and take the map instead of the lane. |
| First item | Even / skill | Her first item feeds the poison DPS and Miasma still zones your engage, but your first MR item eats exactly the damage she deals. |
| Two+ items | Even / skill | At 2+ items her sustained poison out-DPSes your tank-AP trades, yet the stage still reads even: Shield of Durand's amplified reduction answers a purely magic kit, Oblivion Orb kills the Twin Fang heal, and turning your back on Petrifying Gaze drops her stun to a slow. |
Level 1 is a wash: you have only Winds of War with no engage, and she only has Noxious Blast, so contest last-hits, dodge the poison clouds, and bank mana for level 3. The first danger window is 2-3 as her poison ramp comes online — she stacks Noxious Blast and chunks you with Twin Fang on a 0.75s cooldown from outside Justice Punch range, healing off every cast, and a Miasma grounds the dash so you can't punish. The answer is your identity button: channel Shield of Durand into her Twin Fang to gut the magic damage, then release the taunt and E in. Miasma is 24s at rank 1, so the moment she spends it the level is yours.
