Playing against Illaoi
How to counter and exploit weaknesses
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.
NEVER fight Illaoi in her tentacles: lure her elsewhere. Destroy tentacles when you can.
Her R is dangerous with multiple champions nearby — don't group on her. Fight her in a 1v1 outside her zone.
Illaoi has no mobility or hard CC: ganks and kiting are very effective.
