Favour timeline — the windows in Gwen's game plan

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

This is Gwen's own plan; across 612 pooled games the lane is leaning Illaoi.

StageFavouredWhy
Level 1IllaoiIllaoi out-stats you at level 1 and your item-less HP can't survive a Test of Spirit grab plus the tentacles it spawns — farm, don't fight.
Level 2IllaoiShe still owns this window: her E pulls your spirit and chases you with tentacles while you have no W up to make yourself untargetable to her.
Level 3Even / skillWith Q+E you poke and reset, but she is ahead until your mist is online — commit only after a 16s Test of Spirit whiffs.
Levels 4-5Even / skillYou're a melee with no mist uptime versus her tentacle field, so it's a coinflip on who lands cooldowns — keep dodging her E.
Level 6GwenAt 6 you fight inside Hallowed Mist on top of her: it blanks her autos and Harsh Lesson while Needlework slows and your Q out-DPSes the slams — but Leap of Faith grounds your dash.
First itemGwenRiftmaker plus anti-heal let your %-HP and true-damage Snip Snip! out-sustain the lifesteal she gets from slamming you in any extended duel.
Two+ itemsGwenThe more HP and armor she stacks the harder your max-HP passive and magic Q shred her, and her zero mobility means she can't escape your dash-in all-in.

How to beat Illaoi as Gwen: the early game

Levels 1-3 are hers and you have to respect it — Illaoi out-stats you on raw base damage, and a landed Test of Spirit (E, 16s at rank 1) rips your spirit out so tentacles spawn and chase you while you have no W and no items to soak the hits. Spacing alone will not save you: Harsh Lesson is a 4s dash that also resets her auto, so she closes the gap herself and the swing wind-up, not the cast, is your tell. Last-hit with the tip of Snip Snip!, dodge the E, and settle for safe last-hits over poke you cannot afford.
