This is Illaoi's own plan; across 612 pooled games the lane is leaning Illaoi.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Illaoi | Illaoi-favoured: level 1 she has no Mist and can't escape your W trade. |
| Level 2 | Illaoi | Illaoi-favoured: level 2 your slam-empowered W chunks her immobile frame. |
| Level 3 | Illaoi | Skill: Test of Spirit lands at 16s, but her Q is true damage every 6.5s. |
| Levels 4-5 | Illaoi | Skill: levels 4-5 your tentacles punish her, but Hallowed Mist resets it on 22s. |
| Level 6 | Gwen | Gwen-favoured: level 6 Needlework pokes from 1200 while Mist keeps her untargetable. |
| First item | Gwen | Gwen-favoured: first item Nashor's makes her Q out-DPS your slams through the field. |
| Two+ items | Gwen | Gwen-favoured: at 2+ items her Mist uptime and mobility ignore your tentacles entirely. |
You own levels 1-5: Gwen has no Hallowed Mist yet, so W Harsh Lesson in, land E Test of Spirit, and seed tentacles to chunk her before she can scale. Punish every window her W is on cooldown.

Illaoi takes Grasp of the Undying on the Resolve tree with Demolish, Second Wind and Overgrowth, and Precision secondary (Triumph and Legend: Haste) vs Gwen.
Start Doran's Shield + Health Potion and back for Executioner's Calling (≈800g) — cuts her healing. Build Iceborn Gauntlet (the slow makes tentacles land) first, then Sterak's Gage, with Mercury's Treads.
