How to win lane as Cassiopeia against Ryze · 51.85% win rate (2,087 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
He pokes in bursts, you damage in streams — close to Q range on his cooldowns and the DPS war is no contest.
Track: Ryze's W — Rune Prison (11–9s cooldown). Point-blank root — respect the EQ chain that follows it.
Read from Cassiopeia's seat: which stage windows this plan plays for against Ryze.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Your poke and poisoned wave out-trade his costly Overload-Q pattern from level 1 |
| Level 2 | Even / skill | Extended trades favour your poison uptime over his Flux-then-root combo |
| Level 3 | Even / skill | Same story continues as both kits scale similarly but your damage profile is more efficient |
| Levels 4-5 | Cassiopeia | He still can't out-trade you and his Realm Warp roam doesn't threaten your lane presence |
| Level 6 | Cassiopeia | Post-6 Realm Warp is a map tool, not a lane-kill cooldown, so you remain ahead in direct trades |
| First item | Cassiopeia | Your item spikes (DoT + slow) outpace his tanky mana-battery scaling |
| Two+ items | Even / skill | Full-build Cassiopeia deletes him in extended fights while R punishes any flank attempt |
You're favoured from level 1 — Overload reaches 1000 to your 850, but it costs him mana every cast and his root needs Spell Flux on you first, so trade whenever the Flux debuff is not sitting on your health bar. Track Rune Prison (W): 11/10.5/10/9.5/9s at 615 — it only ROOTS if Spell Flux is already on you; otherwise it is a slow.

Cassiopeia, slightly — a 51.85% win rate edge over 2,087 games; execution can flip it.
Mostly — Cassiopeia has a small statistical edge (51.85% win rate), but execution decides this lane far more than the pick does.
Not a hard counter — Cassiopeia has a slight edge (51.85% win rate), and play quality decides the rest.
Cassiopeia takes Conqueror on the Precision tree with Presence of Mind, Legend: Haste and Last Stand, and Sorcery secondary (Manaflow Band and Transcendence) vs Ryze.
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 Mercury's-substitute MR if needed).
