Favour timeline — who owns each window

StageFavouredWhy
Level 1Tahm KenchHis passive An Acquired Taste stuns on the third Tongue Lash stack while you have one ability and no poison ramp — eat two hits stepping up and you lose a free trade.
Level 2Even / skillLevel 2 you get a real Q-prime into Twin Fang, but his E Thick Skin banks the chip as grey health, so the trade is closer to even than winning.
Level 3Even / skillYour full Q-to-E poison combo comes online, yet his grey-health sustain blunts the DoT — you contest the lane but never truly own it.
Levels 4-5Tahm KenchRanks in Q and E let you chain Twin Fangs, but his Thick Skin grey health out-sustains the poison and his passive stun punishes every W you throw to ground him.
Level 6CassiopeiaPetrifying Gaze on a W-grounded Tahm Kench is your one clean kill window — the stun lands before his Abyssal Dive or self-Devour can answer it.
First itemTahm KenchBy first item his raw HP and grey health soak your poison faster than you reapply it, and his Tongue Lash slow keeps you out of Twin Fang range.
Two+ itemsTahm KenchHe builds raw HP while you stay glass and short-ranged — his R Devour eats you mid-combo and his tankiness simply outlasts your poison ramp.

Early game (levels 1–5)

Respect his Q from the first wave, but it is a slow-moving skillshot you can sidestep, not point-and-click — the real threat is his passive, An Acquired Taste, which stuns you on the third stack, so never let a second Tongue Lash land while one is already ticking on you. Stack poison from max range and last-hit with Q's tail end. The brutal truth is his E Thick Skin banks most of your poke as grey health and heals it back the instant he leaves your cloud, so even a clean Q-E trade nets you almost nothing — you are not out-poking this lane, you are surviving it.
