Favour timeline — who owns each window

StageFavouredWhy
Level 1Tahm KenchTongue Lash's range matches her Noxious Blast poke, so you trade Q for Q safely and begin stacking An Acquired Taste while Thick Skin absorbs the poison ticks passively.
Level 2Even / skillHer W Miasma pool grounds your Devour approach — neither side has a clean kill pattern yet, so both players farm and stack cautiously.
Level 3Even / skillShe can kite your 3-stack window with Miasma if you are not disciplined about avoiding the pool, keeping the stun-Devour combo on a hair-trigger rather than a free punish.
Levels 4-5Tahm KenchWithout her W grounding threat you bully her CS timing with Tongue Lash slow stacks, and she lacks the raw damage to punish your passive Thick Skin healing through a full wave.
Level 6CassiopeiaPetrifying Gaze face-stuns any all-in approach — she holds R specifically to answer your 3-stack window, and her Twin Fang DPS at 6 is high enough to punish a stunned Tahm Kench caught walking at her.
First itemTahm KenchHeartsteel or Sunfire pushes your grey-health healing past her sustained Twin Fang output in extended fights — you simply out-last her, force the stun, and Devour before she can disengage.
Two+ itemsTahm KenchAt 2+ items your Thick Skin and tank stats make you near-unkillable in skirmishes — even a full Cassiopeia cannot burn you down before your team collapses on her, and Abyssal Voyage turns every teamfight into a positional nightmare for her backline.

Early game (levels 1–5)

Tongue Lash has the range to contest her Noxious Blast poke — every CS trade you step up and hit her with Q stacks An Acquired Taste for free, and her poison ticks convert straight into Thick Skin grey health you will heal back between waves. Do not walk into her W Miasma pool under any circumstance: it grounds you, cancels your Devour approach, and lets her Twin Fang stack freely while you stand still. The gameplan is simple: Q her for stacks, hold Devour as the threat that keeps her from all-inning you, and heal through the poison in the wave-downtime between trades.
