Read from Cassiopeia's seat: which stage windows this plan plays for against Poppy.
This is Cassiopeia's own plan; across 259 pooled games the lane is leaning Poppy.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | Her Iron Ambassador buckler and W resists beat your lone Level-1 Q before any poison can stack. |
| Level 2 | Even / skill | You even it once you have Q to prime and Twin Fang to follow, but she still trades back through her durability. |
| Level 3 | Even / skill | W Miasma now grounds her E charge mid-dash, so the lane is even — you can finally cancel the wall pin and kite. |
| Levels 4-5 | Even / skill | She walks you down through poison and her hammer poke chips you while the Heroic Charge wall stun looms. |
| Level 6 | Cassiopeia | R Petrifying Gaze stuns her as she commits the all-in, and chaining Twin Fang onto your poison turns her dive into a kill. |
| First item | Even / skill | Roughly even: your Liandry's poke matters but her first tank item and W resists already start eating your magic damage. |
| Two+ items | Cassiopeia | Her MR and HP gut your Twin Fang DPS while E to a wall and R knockback still catch you — a resisted tank flips the lane back. |
Level 1 is Poppy's — her Iron Ambassador hammer poke is point-and-click and her W Steadfast Presence passive resists already tax your single Q before you have any poison ticking. The real danger is E Heroic Charge: charged into a side wall it is a long stun, so stand in open lane and keep off the brush. Last-hit with Q Noxious Blast at max range rather than walking up, and once you hit 3 and unlock W Miasma you can finally ground her E mid-dash and deny the pin.
