At a glance

A dodgeball duel at sniper range — your max-distance Q out-damages her whole rotation if the bubble lands first.

Track: Cassiopeia's W — Miasma (24–16s cooldown). Grounds you — dashes and leaps are disabled inside it.

Do

  • Flick short Qs between bubble windows
  • Bubble through walls and minion gaps
  • Max the Q's travel BEFORE the redirect

Don't

  • Bubble on cooldown into minion block
  • Trade while her key spell is loaded
  • Stand still spinning the Q — you're the target too

How to beat Cassiopeia as Zoe: the early game

Levels 1-2 are yours: Cassiopeia is slow and short-range early, so your E-into-Q punishes every step before her poison ramps. Track Miasma (W): 24s at rank 1, 16s at rank 5 — it grounds, so Portal Jump will not cast inside the cloud. Step up only on its downtime. Early you can bully her: at 1-2 Cassiopeia has no movement speed and low range, so land E (Sleepy Trouble Bubble) into Paddle Star for big chunks before her poison ramps. But by 3-5 her Twin Fang (E) spam plus Miasma (W) zoning flips it — she out-sustains your poke and W lets her deny your bubble angles.
