Track: Cassiopeia's W — Miasma (24–16s cooldown). Grounds you — dashes and movement abilities are disabled inside it.
Read from Tryndamere's seat: which stage windows this plan plays for against Cassiopeia.
This is Tryndamere's own plan; across 443 pooled games the lane is Tryndamere-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is skill-based as her poison poke starts but neither champ has a kill threat. |
| Level 2 | Even / skill | Level 2 stays skill-dependent while her Q and W chip you at farm range. |
| Level 3 | Even / skill | Level 3 is skill-based as her E Twin Fang sustain builds but you can still dodge and farm. |
| Levels 4-5 | Cassiopeia | Level 4 is Cassiopeia's once her full poison rotation and W puddle deny your approach. |
| Level 6 | Even / skill | Level 6 is skill-based since angling around R Petrifying Gaze and your own R keep you alive. |
| First item | Tryndamere | First item is yours as crit autos melt her squishy build once you reach her past W. |
| Two+ items | Tryndamere | With 2+ items you win outright, her poison DPS unable to kill through Undying Rage. |
Levels 1-3 are skill-dependent but lean on Cassiopeia's poison zoning: her Q Noxious Blast and W Miasma chip you every time you step to farm, and her E Twin Fang resets keep her sustained. Play for CS, sidestep her skillshots and avoid extended trades while her kit outranges you.
