Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillLevel 1 is even — she usually has just one point in Tentacle (Q), so swing autos only, watch where she plants tentacles, and don't path into a future grab.
Level 2IllaoiHer Test of Spirit plus a tentacle slam out-damages your level-2 trade, and Counter Strike dodges her autos but not the slams — there is no safe step-up here.
Level 3IllaoiYour full combo is online but dead inside her field; her tentacles out-trade you and a landed Test of Spirit punishes any Leap Strike in, so hold the wave on your side.
Levels 4-5IllaoiShe owns the space around her tentacles — only trade when she is pulled off them and her E is down, otherwise just farm the edge and give up nothing.
Level 6IllaoiLeap of Faith powers the whole tentacle ring and her sustain heals through your burst, and Counter Strike's stun can't cancel the slams — never contest her 6 all-in.
First itemIllaoiHer first-item spike stacks even more field damage and healing while your Trinity/on-hit hasn't tipped the duel yet — keep dodging E and stall the wave.
Two+ itemsJaxWith two items Grandmaster at Arms' Armor/MR plus your on-hit ramp out-duel her in the open — Q onto her off her tentacles, blank her autos with Counter Strike, and run her down.

Early game (levels 1–5)

Test of Spirit (E) is the entire early game: if she rips your spirit you have to run from your own tentacle slams or eat huge damage, so do NOT walk into grab range just to land a Leap Strike. Last-hit from the edge and respect that her tentacles out-trade you anywhere near them. The trap is thinking Counter Strike saves you — it dodges her basic attacks but not the slams, so popping E while you stand in her field does nothing. Farm safe, hold Counter Strike to body-block a spirit pull and disengage, and accept you are behind on lane pressure until you have items.
