How to win lane as Cassiopeia against Zed · 48.01% win rate (2,091 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Miasma turns assassins off — ground the dash, petrify the dive, and fang the helpless body that was supposed to one-shot you.
Track: Zed's R — Death Mark (120–100s cooldown). The all-in — spend your defensive answer AFTER the mark lands, not before.
Read from Cassiopeia's seat: which stage windows this plan plays for against Zed.
This is Cassiopeia's own plan; across 2,091 pooled games the lane is leaning Zed.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Level 1 favors you outright because Zed has zero safe way to close distance against your ranged poke without eating free damage. |
| Level 2 | Even / skill | Level 2 stays yours as your poke chip continues to outpace anything he can answer with at this stage. |
| Level 3 | Even / skill | Level 3 is a bigger spike for you since your full combo lets you zone him completely off the wave. |
| Levels 4-5 | Cassiopeia | Levels 4-5 remain in your favor as sustained poke keeps him below the HP threshold needed for any all-in attempt. |
| Level 6 | Even / skill | Level 6 flips to him because Death Mark is a genuine burst threat and his best all-in window of the entire game. |
| First item | Even / skill | Your first item swings it back — Seraph's DoT output alone threatens to kill him inside the three seconds his mark needs. |
| Two+ items | Cassiopeia | Late-game 2+ item fights stay in your favor overall since your zone control and burst still outclass him unless he's significantly ahead. |
Levels 1-2 heavily favor you since Zed has no way to engage safely into your Noxious Blast poke, and every trade he tries to force gets answered by ground-zone damage before he can even get in range with Shuriken. By level 3 your full combo lets you zone him off the wave entirely — Miasma denies the square he needs to close distance, and he's forced into passive farming under constant chip damage.

Start Doran's Ring + 2 Health Potions and back for Tear of the Goddess + Dark Seal (≈800g). Build Seraph's Embrace first, then Liandry's Torment, with No boots — passive move speed (slot goes to armor/Zhonya's earlier).
