Favour timeline — who owns each window

StageFavouredWhy
Level 1HeimerdingerHis first turret plus W rockets out-range my lone Q and chip me off the wave before I have any Q/W poison stacked to trade back.
Level 2Even / skillOnce I have Q and E I can poison-and-Twin-Fang, but his rocket poke and turret chip still match my damage at this range — it stays even.
Level 3Even / skillMy Q-cloud into Twin Fang and the Q move-speed buff let me weave through turret fire, but his nest and stun grenade keep it a genuine skill fight.
Levels 4-5CassiopeiaRanks in Q and E let me chain Twin Fangs on a poisoned Heimer while my W slow-and-ground holds him for the trade — I win the extended fight if I dodge the grenade.
Level 6CassiopeiaPetrifying Gaze stuns him for a full Twin-Fang chain when he's facing me, turning a primed Q poke into a kill if I bait his E first.
First itemEven / skillMy Liandry's plus passive MS-to-AP shreds him, but his turret wall blunts my short-range all-in — I have to clear or path around the nest, keeping it even.
Two+ itemsHeimerdingerHe out-scales into a siege and pick threat: an R-empowered E grenade bursts boots-less, resist-less me before Twin Fang ramps, so the lane tilts back to him.

Early game (levels 1–5)

Level 1-2 is his — his turret plus W rockets out-range and out-poke my single Q, and I have no Q/W poison stacked yet to trade back. I farm with the tip of Q and eat a little chip rather than walking into the nest. The lane swings the moment I have Q and E together at 3: I throw Q across both him and his turrets, then Twin Fang whatever's poisoned, and the Q move-speed buff lets me peel out of rocket range before his grenade lands. Dodge the E — it's slow and telegraphed, and if I sidestep it his only follow-up is turret autos.
