Read from Olaf's seat: which stage windows this plan plays for against Illaoi.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Olaf | Level 1 a fieldless Illaoi has no tentacles, so your Q-slow-into-auto wins first contact outright. |
| Level 2 | Even / skill | Once Test of Spirit is up the trade evens — she rips your spirit, but Undertow's slow and your shield still hold. |
| Level 3 | Illaoi | Her tentacle stacks and the healing off them out-last your lifesteal, and punish every Reckless Swing you throw. |
| Levels 4-5 | Illaoi | Levels 4-5 she has a real field up — Test of Spirit plus tentacle slams beat your short trades and heal it all back. |
| Level 6 | Olaf | Ragnarok keeps you disable-immune while you keep swinging in her field — this is your all-in and dive window. |
| First item | Illaoi | At first item her tentacle stacks and AOE healing reclaim the lane — her field out-heals anything you can dish out. |
| Two+ items | Even / skill | At 2+ items it is a knife-edge: you must pull her off her tentacles and burst her, or her stacked field wins the brawl. |
Level 1 is yours: throw Q for the slow and walk an auto in before she has a single tentacle planted, because a fieldless Illaoi has no answer to a stuck axe. But the moment she has E up this flips — do NOT facetank a trade next to her tentacles, and never let her land Test of Spirit on you, or you spend the trade running from your own spirit-vessel while her tentacles slam and heal her. Last-hit at Q range, pick the axe back up to chain slows, and refuse the extended brawl she wants.

Start Doran's Blade + Health Potion and back for Executioner's Calling (≈800g) — cuts her healing. Build Sundered Sky (sustain spike) first, then Sterak's Gage, with Plated Steelcaps.
