How to win lane as Trundle against Cassiopeia · 58.23% win rate over 79 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Trundle | Q Chomp steals her Attack Damage on the very first auto of the game — she cannot fight back evenly and your passive heals off the wave, so level 1 belongs to you. |
| Level 2 | Cassiopeia | She hits level 2 and can now alternate Q Noxious Blast with W Miasma to ground you and set up Twin Fang chains safely from range — the poke advantage shifts to her. |
| Level 3 | Cassiopeia | At level 3 she has Q+W+E online: poison into Twin Fang into grounding zone is a full combo that beats your melee engage unless you have perfect Pillar timing. |
| Levels 4-5 | Even / skill | Levels 4-5 are a genuine contest — your Chomp AD theft and Frozen Domain sustain match her poke output if you respect Miasma, but neither of you has a clean kill window. |
| Level 6 | Even / skill | Level 6 is hers: Petrifying Gaze R stuns you if you walk at her face-on and she can burst through Frozen Domain before your Subjugate drain reaches critical mass. |
| First item | Cassiopeia | Her first AP item (Luden's or Shadowflame) amplifies Q Noxious Blast damage and Twin Fang burst to the point where sustained poke wins the war of attrition — she controls this window. |
| Two+ items | Trundle | At 2+ items your Subjugate drain strips enough of her Magic Resistance that an extended Frozen Domain brawl tips back in your favour — force the long melee fight and drain her scaling away. |
At level 1 you are the aggressor — Q Chomp on the first auto steals her Attack Damage and slows her attack speed, so do not sit back and let her establish a poke pattern with Noxious Blast. Step onto Frozen Domain W and walk up for a second Chomp the moment Q resets; she has no mobility and every second of extended auto-trading shifts further in your favour. Your passive King's Tribute heals off every minion that dies nearby, meaning her early poison ticks do not accumulate the way they do against immobile tanks — you regenerate faster than she can whittle. The real threat is her W Miasma grounding zone: she will drop it in front of you to slow your advance and trigger Twin Fang chains from poison. Respect the Miasma placement and path around it rather than running into the ground effect.
