How to win lane as Cassiopeia against Trundle · 41.77% win rate (79 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
A DPS check he fails — poison every step-up, ground his approach, and E-spam him off the wave.
Track: Trundle's R — Subjugate (120–80s cooldown). Steals your resists and HP — never take a long duel into it.
Read from Cassiopeia's seat: which stage windows this plan plays for against Trundle.
This is Cassiopeia's own plan; across 79 pooled games the lane is Trundle-favoured.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Trundle | Level 1 you have one ability and no poison stacking, while his Chomp (Q) saps your attack damage and a Pillar (E) angle out-trades your single Noxious Blast. |
| Level 2 | Cassiopeia | At level 2 your prime-and-Twin-Fang (Q into E) trade beats his early sustain before Frozen Domain's heal zone comes online. |
| Level 3 | Cassiopeia | Level 3 my full Q-poison into repeatable E-spam is real DPS he cannot yet out-heal — my clearest lane edge. |
| Levels 4-5 | Even / skill | Ranks in Q and E push my treadmill, but his Frozen Domain (W) heal zone and passive regen pull the extended trade back to even. |
| Level 6 | Even / skill | Petrifying Gaze stuns his all-in, yet Subjugate (R) stealing my resistances and healing him keeps the level-6 fight a coin-flip. |
| First item | Cassiopeia | My Liandry's/Malignance tick out-damages his sustain for a window, and this first-item spike is my clearest edge before he stacks tank. |
| Two+ items | Trundle | His Subjugate (R) plus drain-tank items let him heal through my full poison rotation and walk me down — I stop killing him first. |
Level 1 is his — Chomp (Q) saps your attack damage every 3.5s and a Pillar (E) angle out-trades your single Noxious Blast before you stack any poison. From level 2 the lane flips to you: prime with Q, then chain Twin Fang (E) off the poison for cheap, near-continuous damage and chip him before Frozen Domain's attack-speed-and-heal zone and his passive regen switch on. Do not over-commit for the kill — his kit is built to out-heal a slow poke war, so buy Grievous Wounds early and bank the lead in CS and plates instead.

Start Doran's Ring + 2 Health Potions and back for Oblivion Orb (≈800g) — cuts his healing. Build Seraph's Embrace / Liandry's Torment first, then Rylai's Crystal Scepter, with No boots — bank the gold into Zhonya's earlier.
