How to play Zac in ARAM Mayhem

Zac is one of the weakest picks in ARAM Mayhem on patch 26.21: tier D, #170 of 173 champions, with a 44.5% win rate over 554,899 games. Riot rates it 8/10 for difficulty, so give it a few games before you judge it.

73% of Zac's damage to champions is magic, so enemy magic resist is what slows it down. It soaks 85,930 damage per game and mitigates another 99,899, so it belongs at the front: start fights and absorb the poke your carries can't.

The Tank build, tank items, is both the most played and the top-ranked path: Heartsteel, Unending Despair and Warmog's Armor, with a 46.4% win rate over 375,186 games. On this build 61% of players skip boots and spend the slot on another item.

The cards that do best on Zac are Circle of Death, Hand of Baron and Upgrade Immolate. Cards built around health and resistances fill most of the top of its list. Skip Urf's Champion and Flashbang when you can: they do worst on Zac. A pair to look for: Circle of Death with Forged By The Master.

Take Flash and Mark (93% of players). Max E (Elastic Slingshot) first, then W, then Q.
