How to play Jax in ARAM Mayhem

Jax is one of the strongest picks in ARAM Mayhem on patch 26.21: tier S, #15 of 173 champions, with a 53.8% win rate over 1,483,822 games.

Jax's damage is mixed (51% physical, 44% magic), which makes it awkward for the enemy team to itemize against. It soaks 48,837 damage per game and mitigates another 56,151, so it belongs at the front: start fights and absorb the poke your carries can't. It dies 13.4 times per game on average: it trades its life for impact, so time your engages with your team.

Most Jax players go Bruiser (45% of games), but the AP path, ability power items, is ARAMKit's top-ranked build: Dusk and Dawn, Riftmaker and Nashor's Tooth, with a 54.8% win rate. On this build 43% of players skip boots and spend the slot on another item.

The cards that do best on Jax are Take'em Down Down Down, The Boom and the Bass and Armored Impact. Cards built around ability haste fill most of the top of its list, followed by movement speed. Most of its S-tier cards are prismatic, so a prismatic offer is often the pick that shapes the game. Skip Squishy Slappy Grab and It's Killing Time when you can: they do worst on Jax. A pair to look for: The Boom and the Bass with Take'em Down Down Down.

Take Flash and Mark (95% of players). Max W (Empower) first, then Q, then E.
