Read from Tahm Kench's seat: which stage windows this plan plays for against Sejuani.
This is Tahm Kench's own plan; across 438 pooled games the lane is leaning Sejuani.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Tongue Lash starts An Acquired Taste stacking, but the slow on it is dead weight — Frost Armor makes her immune to slows out of combat, and Frost begins building on you from her first retaliatory auto. |
| Level 2 | Even / skill | Once Frost is maxed on you, Permafrost stuns at will on a 1.5s cooldown — there is no window to wait out, so the only defence is denying the Frost stacks themselves. |
| Level 3 | Tahm Kench | Her Permafrost stun into a Fury of the North shatter is the real burst, and it lands as one lump rather than as chip — Thick Skin banks grey health it never gets to convert. |
| Levels 4-5 | Even / skill | Abyssal Dive is your one opener she cannot blunt — Frost Armor stops slows, never knockups — but land it and you are stood next to a Sejuani free to Frost you to maximum at her leisure. |
| Level 6 | Even / skill | Her R reactively cancels your Devour commit — the moment you lock in the 3-stack animation she drops the AOE stun, wastes your W cooldown, and walks away with the trade won. |
| First item | Tahm Kench | Heartsteel and Sunfire increase your raw bulk, but Sejuani's W percent-current-HP damage scales with your growing HP pool, meaning your item spike actively makes her W ticks hit harder relative to your healing. |
| Two+ items | Tahm Kench | In full teamfights her R controls the whole map while your Devour removes one target — she out-scales your single-target lockdown and owns the late teamfight entirely. |
At level 1 your Tongue Lash pokes but does not kite: Sejuani sits on Frost Armor whenever she has been out of combat, and Frost Armor is flat immunity to slows. The stack still applies, so treat Q as a stack-builder here and nothing else. Step up to last-hit and let Thick Skin bank her retaliatory autos, but watch the Frost counter on your own bar — at maximum, Permafrost stuns you whenever she wants, and her passive shatters a stunned target hard. Her Arctic Assault charge is 18 seconds at rank 1 and stops dead on the first champion it touches, so that is the only cooldown here worth counting. Keep her in combat and Frost Armor cannot come back, which is the only way your slow ever matters.
