Illaoi's abilities

Passive, spells and ultimate

Prophet of an Elder God (P)

Illaoi and the Vessels she creates spawn Tentacles on nearby impassible terrain. Tentacles swing at spirits, Vessels, and victims of Illaoi's Harsh lesson. Tentacles deal physical damage to enemies hit, and will heal Illaoi if they damage a champion.

Playing against Illaoi

How to counter and exploit weaknesses

1

Dodge her E (Test of Spirit) at all costs — if she pulls your spirit, you must flee the area or fight at a massive disadvantage.

2

NEVER fight Illaoi in her tentacles: lure her elsewhere. Destroy tentacles when you can.

3

Her R is dangerous with multiple champions nearby — don't group on her. Fight her in a 1v1 outside her zone.

4

Illaoi has no mobility or hard CC: ganks and kiting are very effective.
