| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Illaoi | Illaoi's Test of Spirit and tentacle smashes out-grind your level-1 kit. |
| Level 2 | Illaoi | At level 2 her tentacle field and E reset keep every trade hers. |
| Level 3 | Illaoi | Level 3 her full tentacle DPS overwhelms you in any extended fight. |
| Levels 4-5 | Illaoi | Levels 4-5 she still wins trades near her tentacles and pressures the wave. |
| Level 6 | Illaoi | At 6 Leap of Faith can delete you if boxed in beside her tentacles. |
| First item | Zac | By first item your tank stats let you survive and leave her ult zone. |
| Two+ items | Zac | Late, your mobility and tankiness ignore an immobile tentacle-bound Illaoi. |
Illaoi bullies levels 1-3 — dodge Test of Spirit at all costs, because a hit spirit plus her tentacle smashes will chunk you out of lane; farm from range and never trade in her field.
