Read from Sylas's seat: which stage windows this plan plays for against Cassiopeia.
This is Sylas's own plan; across 325 pooled games the lane is leaning Sylas.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | She starts Noxious Blast and Twin Fang at level 1 and you have no dash yet — last-hit at Q range and bank the HP lead for when E comes online. |
| Level 2 | Cassiopeia | Her Miasma Grounds your E dash the instant you step forward — she erases your only engage tool and pokes freely all level 2. |
| Level 3 | Cassiopeia | Full kit does not help you if Miasma covers your hook angle — she wins every level 3 skirmish you initiate without Miasma on cooldown. |
| Levels 4-5 | Cassiopeia | Twin Fang hits poisoned targets harder and heals her off the damage — buy Grievous Wounds or she simply wins the levels 4-5 attrition war. |
| Level 6 | Even / skill | Hijack grants Petrifying Gaze — land the face-stun into Q-W-passive burst and the kill is yours, but she can still Miasma the approach to nullify it. |
| First item | Cassiopeia | Riftmaker burn stacks in your W and passive autos, but only when you reach her; Miasma still counters your first-item all-in pattern if it is up. |
| Two+ items | Cassiopeia | Full-build Cassiopeia Twin Fang loops out-DPS your W healing and Seraph's keeps her sustained — avoid the extended 1v1 unless her R is confirmed on cooldown. |
Level 1 you have no safe engage — Q range barely reaches her and she can immediately answer every step-up with Noxious Blast into Twin Fang chains. Walk up only to last-hit and accept losing some CS to her Q poke rather than burning E1 for a chase she simply kites away from. The real danger is Miasma: she will drop it in your path the moment you look to step up at level 2, Grounding your E dash entirely and leaving you stranded in melee range with no escape. Learn her Miasma cooldown — roughly 24 seconds base — and only commit to the E2 hook in the window immediately after it fades.
