Favour timeline — who owns each window

StageFavouredWhy
Level 1TrundleLevel 1 I have one ability and no poison stacking, while his Chomp (Q) steals my attack damage and a Pillar (E) angle out-trades my single Noxious Blast.
Level 2CassiopeiaAt level 2 my prime-and-Twin-Fang (Q into E) trade beats his early sustain before Frozen Domain's heal zone comes online.
Level 3CassiopeiaLevel 3 my full Q-poison into repeatable E-spam is real DPS he cannot yet out-heal — my clearest lane edge.
Levels 4-5Even / skillRanks 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 6Even / skillPetrifying Gaze stuns his all-in, yet Subjugate (R) stealing my resistances and healing him keeps the level-6 fight a coin-flip.
First itemCassiopeiaMy 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+ itemsTrundleHis Subjugate (R) plus drain-tank items let him heal through my full poison rotation and walk me down — I stop killing him first.

Early game (levels 1–5)

Level 1 is his — he has Chomp (Q) stealing my attack damage plus a Pillar (E) angle, and that out-trades my single Noxious Blast (Q) before I can stack any poison. From level 2 the lane flips to me: I prime with Q, then chain Twin Fang (E) off the poison for cheap, near-continuous damage and chip him before his Frozen Domain (W) attack-speed-and-heal zone and passive sustain switch on. Do not over-commit for the kill — his whole kit is built to out-heal a slow poke war, so bank the lead in CS and plates instead of forcing a fight he can sustain through.
