How to play Illaoi in ARAM Mayhem

Illaoi is a below-average pick in ARAM Mayhem on patch 26.21: tier C, #143 of 173 champions, with a 46.6% win rate over 829,415 games.

89% of Illaoi's damage to champions is physical, so enemy armor is what slows it down. It soaks 81,857 damage per game and mitigates another 93,363, so it belongs at the front: start fights and absorb the poke your carries can't. It brings almost no crowd control, so it relies on teammates to set up kills.

Most Illaoi players go Tank (64% of games), but the Bruiser path, bruiser items that mix damage and health, is ARAMKit's top-ranked build: Heartsteel, Overlord's Bloodmail and Sundered Sky, with a 47.3% win rate. On this build 59% of players skip boots and spend the slot on another item.

The cards that do best on Illaoi are Mad Scientist, Steel Your Heart and Goliath. Cards built around ability haste fill most of the top of its list, followed by health and resistances. Skip Quickstep and Don't Blink when you can: they do worst on Illaoi. A pair to look for: Goliath with Steel Your Heart.

Take Flash and Mark (94% of players). Max E (Test of Spirit) first, then Q, then W.
