How to play Jayce in ARAM Mayhem

Jayce is a below-average pick in ARAM Mayhem on patch 26.21: tier C, #134 of 173 champions, with a 47.1% win rate over 1,989,936 games. It is also one of the most picked champions, showing up in 9% of games, so expect to see it on both sides.

75% of Jayce's damage to champions is physical, so enemy armor is what slows it down.

Most Jayce players go Lethality (63% of games), but the Crit path, critical strike and attack speed items, is ARAMKit's top-ranked build: Hubris, The Collector and Infinity Edge, with a 47.1% win rate. On this build 64% of players skip boots and spend the slot on another item.

The cards that do best on Jayce are Hand of Baron, Weapon of Destiny and Mad Scientist. Cards built around ability haste fill most of the top of its list, followed by movement speed. Skip Pursuit of Power and Flashbang when you can: they do worst on Jayce. A pair to look for: Mad Scientist with Weapon of Destiny.

Take Flash and Mark (85% of players); Ghost is the common alternative. Max Q (To the Skies! / Shock Blast) first, then E, then W. Players who max Q first instead win a little more often, so it is worth trying.
