Jayce Item Build
Each of Jayce's cannon shots should take a real bite out of a health bar rather than tickle it, so his build stacks lethality and attack damage. The Abyss opens with a long poke phase before anyone commits, so it rewards burst per shot over sustained fighting, sharpening the range advantage he uses to soften a grouped team ahead of the all-in the single bridge forces.
Best Jayce Runes
Dark Harvest headlines the poke war Jayce dominates on the Abyss, where he chips a grouped team from max range with cannon form between fights. He is threading Shock Blasts across the choke rather than committing early, so build around the mana and cooldowns that keep the long-range poke landing shot after shot.

Jayce Skill Order
Hyper Charge is what the Abyss order starves: maxed second on the Rift, it collects nothing between the opening allocation and level 14. Thundering Blow and Acceleration Gate take those points instead, ranking at 6, 8, 10, 12 and 13, where range and knockback pay better than a burst of attack speed.
Jayce ARAM Abilities
Underneath the bully act sits a defensive side. Thundering Blow knocks an enemy back and away from his carry, the Mercury Hammer swap layers on Armor and Magic Resist as he dives, and Hextech Capacitor hands him a speed burst on every weapon change to reposition.
