Track: Cassiopeia's W — Miasma (24–16s cooldown). Grounds you — dashes and movement abilities are disabled inside it.
Read from Ornn's seat: which stage windows this plan plays for against Cassiopeia.
This is Ornn's own plan; across 851 pooled games the lane is Ornn-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Cass has no Twin Fang stacks and is as weak as you at Level 1 — just last-hit and don't walk into Q poison range. |
| Level 2 | Cassiopeia | Her Q poison plus early Grounding W out-trades you before your combo exists — she edges the level-2 poke war. |
| Level 3 | Cassiopeia | She free-poisons you while you wait on your W, and her W grounds any early E engage you try. |
| Levels 4-5 | Cassiopeia | She out-DPSes your trades with stacked Twin Fang and kites your telegraphed E-Q with passive move speed. |
| Level 6 | Cassiopeia | Even your R all-in window is contestable — her R face-stun and Grounding W can blank the double knock-up. |
| First item | Cassiopeia | Her first AP item ramps her poison DPS faster than your tank spike can punish a kiting, grounding mage. |
| Two+ items | Cassiopeia | Full-AP Cass grounds every dash, kites freely, and melts your armor stacking with percent-poison DPS. |
Cassiopeia is mana-starved and stuck shoving for her own Twin Fang stacks early, and you are an even weaker Level 1, so just farm and soak her Q poison rather than walking up. The danger is her W grounding — it cancels your E dash mid-flight, so do NOT throw out E-Q to engage at Levels 1-2 or you'll get grounded and poisoned for free. Hard-shove the wave with W's percent-HP poke once you hit 3 and look to crash before her sustained DPS ramps.
