Favour timeline — the windows in Illaoi's game plan

Read from Illaoi's seat: which stage windows this plan plays for against Dr. Mundo.

Stage	Favoured	Why
Level 1	Illaoi	You win level 1 — his Bonesaw at 975 range only chips while tentacles swing free.
Level 2	Illaoi	Level 2 stays yours — Harsh Lesson resets your auto and drags tentacle swings.
Level 3	Illaoi	Level 3 is yours once Test of Spirit lands — damage echoes back.
Levels 4-5	Illaoi	Levels 4-5 you keep control — Heart Zapper's 15s cooldown is your fight window.
Level 6	Illaoi	Level 6 Leap of Faith spawns a tentacle per champion hit — Dosage peels none.
First item	Illaoi	First item plus Executioner's Calling stops his stored-damage heal keeping up.
Two+ items	Dr. Mundo	Two-plus items even out: full-tank HP and Maximum Dosage healing race your Spirit.

How to beat Dr. Mundo as Illaoi: the early game

You dominate the opener. Mundo's Q Bonesaw is his only poke and it drains his own health, so you win every exchange with tentacle smashes while he can't punish you back. Bully him off the wave.
