How to play Heimerdinger in ARAM Mayhem

Heimerdinger is a solid, middle-of-the-pack pick in ARAM Mayhem on patch 26.21: tier B, #64 of 173 champions, with a 50.4% win rate over 802,077 games. Riot rates it 8/10 for difficulty, so give it a few games before you judge it.

94% of Heimerdinger's damage to champions is magic, so enemy magic resist is what slows it down. It dies only 9.4 times per game on average, fewer than most.

The AP build, ability power items, is both the most played and the top-ranked path: Blackfire Torch, Liandry's Torment and Rabadon's Deathcap, with a 49.7% win rate over 592,628 games. On this build 43% of players skip boots and spend the slot on another item.

The cards that do best on Heimerdinger are Wooglet's Witchcap, Weapon of Destiny and Hand of Baron. Cards built around movement speed fill most of the top of its list, followed by ability haste. Skip Upgrade Sheen and Spin Me Right Round when you can: they do worst on Heimerdinger. A pair to look for: Mountain Soul with Wooglet's Witchcap.

Take Flash and Ghost (55% of players). Max Q (H-28 G Evolution Turret) first, then W, then E.
