Favour timeline — the windows in Swain's game plan

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

This is Swain's own plan; across 802 pooled games the lane is Illaoi-favoured.

StageFavouredWhy
Level 1Even / skillIllaoi's Level 1 Q (Tentacle Smash) hits hard and begins covering the lane — stay just outside tentacle range, farm with Q range, and build no early trades.
Level 2Even / skillHer Test of Spirit (E) is online at Level 2 — if it lands on you back off your spirit immediately; fighting your own tentacles before you have R is a death sentence.
Level 3SwainYour W-into-E lands in open lane at Level 3, but Harsh Lesson leaps to a target every 4 seconds — root her only where no tentacle can answer the pull.
Levels 4-5Even / skillTentacles keep growing off her passive on the walls beside your usual standing spots — commit E only when the root lands clearly away from every one of them.
Level 6SwainLeap of Faith makes her untargetable as it lands, so do not spend R into the cast — wait the window out, then drain her through the tentacle barrage that follows it.
First itemSwainLiandry's Torment burning her max-HP pool outpaces tentacle healing — force W-poke trades constantly and her sustain advantage disappears.
Two+ itemsEven / skillTwo-item Illaoi with deep tentacle coverage is nearly unkillable in a planted field; kite her with W to prevent chase and take the game through objective pressure rather than solo kills.

How to beat Illaoi as Swain: the early game

At Level 1 you both have one ability — her Q (Tentacle Smash) hits harder and she can start placing tentacle coverage, so respect the field she is building and do not walk under a tentacle waiting to slam. At Level 2 E comes online and she also gets Test of Spirit; this is the danger window, not yours — if she lands E on you, back off your spirit immediately, burning Flash if needed, because fighting your own tentacles at Level 2 with no R is how you die. Level 3 is your first real statement: W the ground just inside her comfortable step-up range, and the moment she tries to punish your poke she walks into your E-root in the open. Root in a spot with no tentacles nearby, pull her toward you with the passive, Q the full burst — she eats the combo with no healing and you bank a fragment. The entire early game hinges on never being rooted in her tentacle field yourself.
