Read from Ryze's seat: which stage windows this plan plays for against Cassiopeia.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Cassiopeia's Noxious Blast poke and fast wave push shove you under tower at level 1. |
| Level 2 | Even / skill | At level 2 you both trade spells evenly with no kill threat on either side. |
| Level 3 | Even / skill | At level 3 you can Rune Prison and Overload-burst her before her Twin Fang fully ramps. |
| Levels 4-5 | Cassiopeia | Her Miasma slow at 4-5 zones you and fuels sustained Twin Fang trades you lose. |
| Level 6 | Cassiopeia | Petrifying Gaze at 6 face-checks and hard-counters your engage from range. |
| First item | Cassiopeia | Her first-item Twin Fang ramp DPS still scales harder than your early spike. |
| Two+ items | Even / skill | Full-build Ryze finally out-bursts her before her ramping DPS takes over. |
Cassiopeia pushes first with Noxious Blast, shoving you under tower and poking as you last-hit; level 2 is even as you both trade spells without a kill threat, so soak XP and dodge her Q. Track Cassiopeia Miasma: 24s at rank 1 — the slow feeds her Twin Fang ramp; step up only when it's down. Level 3 is your one clean window before her ramp: Rune Prison her when she steps up to Twin Fang and dump Overload plus Spell Flux, but from level 4 her Miasma slow zones you and fuels sustained Twin Fang DPS you cannot trade back into.
