How to win lane as Fizz against Cassiopeia · 53.98% win rate (1,258 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
You are the reason her class dodges queues — fish through the wave, hop the one answer, and erase her at 6.
Track: Cassiopeia's W — Miasma (24–16s cooldown). Grounds you — dashes and leaps are disabled inside it.
Read from Fizz's seat: which stage windows this plan plays for against Cassiopeia.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Fizz | You dominate lane trades from level 1 since she has no dash to escape your jump-ins |
| Level 2 | Even / skill | Your all-in threat only grows as your combo comes online faster than her poison stacks can punish you |
| Level 3 | Fizz | You keep winning extended trades because her damage ramps slower than your burst threshold |
| Levels 4-5 | Fizz | Your combo still outpaces her kiting even as she adds Rylai's slow for zoning |
| Level 6 | Even / skill | Ult bypasses her only real defense (facing-dependent Petrify) by letting you engage from unexpected angles |
| First item | Fizz | Your burst item spike kills her outright before her survivability items come online |
| Two+ items | Fizz | Her total lack of mobility keeps this matchup in your favor even as she scales into teamfight zone control |
You win this matchup decisively from level 1. Cassiopeia has no dash or blink, so once you're in E range her only defense is landing a facing-dependent Petrify, and if she whiffs it you finish the trade with Q-AA-W well before her poison stacks matter. Track Miasma (W): 24s at rank 1, 16s at rank 5 — grounded, both Urchin Strike and Playful/Trickster are dead. Step in the moment it fades.

Fizz takes Electrocute on the Domination tree with Sudden Impact, Grisly Mementos and Ultimate Hunter, and Precision secondary (Presence of Mind and Coup de Grace) vs Cassiopeia.
Start Doran's Shield + Health Potion and back for Oblivion Orb (≈800g) — cuts her sustain. Build Stormsurge / Rocketbelt first, then Zhonya's / Rabadon's path, with Mercury's Treads / Sorcerer's.
