Read from Tahm Kench's seat: which stage windows this plan plays for against Illaoi.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Tahm Kench | Both kits are feeling each other out — Tongue Lash range lets you poke for stacks without entering Harsh Lesson distance, and Thick Skin starts converting her passive tentacle slaps immediately. |
| Level 2 | Illaoi | Illaoi's W (Harsh Lesson) is live — a 400-range dash on a flat 4s cooldown that resets her auto and slams with it; trade only from Tongue Lash max range. |
| Level 3 | Illaoi | With 3 An Acquired Taste stacks and a missed Test of Spirit, Tongue Lash stuns her and Devour physically removes her from every tentacle she just set up — her cooldowns run out with nothing to show. |
| Levels 4-5 | Illaoi | No ultimates, tentacles are accumulating, and a single misstep inside her field trades your HP bar for nothing — fish stacks from distance and shove wave when she is not threatening E. |
| Level 6 | Illaoi | Illaoi's R (Leap of Faith) spawns a ring of tentacles and resets Harsh Lesson mid-trade — if she pops it while you are chunked you die inside the ring; back out at the all-in health threshold. |
| First item | Illaoi | Heartsteel or Sunfire Aegis amplifies your Thick Skin grey-health conversion — you start healing back a meaningful chunk after short trades, narrowing the window where her tentacle poke sticks. |
| Two+ items | Illaoi | Illaoi's tentacle field in a side lane makes her a late-game split-push threat you cannot 1v1 inside; your role is Devour-peel in teamfights and Tongue Lash harassment on the perimeter of her zones. |
At level 1 both of you are feeling each other out — Tongue Lash's range lets you poke and start building An Acquired Taste stacks from outside Illaoi's melee threat, and Thick Skin begins banking that poke immediately. The moment she hits 2 and gets Harsh Lesson, she can dash into you and trigger a tentacle slam in a single fluid motion, so stop auto-weaving at that point and trade only with Tongue Lash slow from range. Level 3 is your first real punish: if she burns Test of Spirit and misses — or you sidestep it — and you are sitting on 3 stacks, Tongue Lash stuns her, Devour removes her from the field entirely, and every tentacle she just positioned does nothing while the cooldowns run out. That sequence is the whole early-game script: bait the E, punish the whiff.
