Read from Xerath's seat: which stage windows this plan plays for against Cassiopeia.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Xerath | Cassiopeia has no boots and shorter range, so your level 1 Q pokes her freely. |
| Level 2 | Xerath | Level 2 she still can't reach you to trade while you chunk her step-ups. |
| Level 3 | Xerath | Level 3 E and W-slow keep her outside Twin Fang range entirely. |
| Levels 4-5 | Xerath | Levels 4-5 your spacing denies her sustain damage as she can't close safely. |
| Level 6 | Xerath | Level 6 your ult punishes her from off-screen while her R needs close range. |
| First item | Xerath | On first item your range keeps her eating poke on every approach. |
| Two+ items | Even / skill | Late your poke and E peel out-space her ramp on an immobile champion. |
Levels 1-2 you dominate: Cassiopeia is short-range and boot-less, so your Q and W punish every approach and she cannot trade back from where she needs to stand to farm. Track Cassiopeia Miasma: matchup-defining — a 24s-cooldown slow zone at rank 1; while it is down her walk-up threat is gone. Cassiopeia has no boots and short range, so she must physically walk into your Q and W to do anything. Poke her every time she creeps up to Q the wave, and W-slow her so she can never close to Twin Fang (E) range.
