Favour timeline — who owns each window

StageFavouredWhy
Level 1GangplankHis Parrrley and a barrel out-range my lone Noxious Blast and I have no poison engine yet — he chips me for free while I just last-hit.
Level 2Even / skillI get a second ability and can prime-and-Twin-Fang, but his Parrrley poke trades roughly even before my combo fully ramps.
Level 3CassiopeiaMy full Q-into-E poison chain comes online — Twin Fang refunds off Noxious Blast and out-DPSes his single Parrrley poke.
Levels 4-5CassiopeiaRanks in Q and E let me chain Twin Fangs through any extended trade his single barrels cannot sustain or heal off.
Level 6CassiopeiaPetrifying Gaze stuns him out of a barrel-Parrrley all-in and my refunding Twin Fangs finish before Remove Scurvy heals it back.
First itemGangplankHis first Sheen-empowered Parrrley crit lets him trade back into my AP-and-move-speed spike — the window is genuinely even.
Two+ itemsGangplankHis crits, Sheen-Parrrley poke and global R out-itemize my short range, and Remove Scurvy cleanses the Miasma slow I depend on.

Early game (levels 1–5)

Level 1 is his — Parrrley plus a barrel out-range my single Noxious Blast and I have no poison engine yet, so I just last-hit at the edge of my Q and eat a little chip. The lane swings the moment I hit level 3 and have a real Q-into-E chain: when he walks up to place or detonate a barrel, I land Noxious Blast on him, Twin Fang refunds off the poison, and I can keep firing it. Do not let him Parrrley-poke me at range for free, and never sit on a barrel — but punish every step he takes into my poison.
