Jayce Strengths

  • Flexibility from switching between Cannon (ranged) and Hammer (melee) forms
  • Long-range poke from out of vision with Shock Blast
  • High burst damage from the early game

Jayce Weaknesses

  • ×High mechanical difficulty from managing form swaps
  • ×No traditional Ult, so no level 5 power spike
  • ×Tends to fall off as the game goes late

Early Game

Switch between Cannon and Hammer forms to take control of the lane. Chip away with the Skill 3 into Skill 1 combo (Shock Blast) from range, then jump in with Hammer form when an opening appears.

Mid Game

As the core of a poke comp, fire the Skill 3 into Skill 1 combo from out of vision or over walls. Chunking enemy HP before Dragon and Herald fights is Jayce's main role.

Late Game

In teamfights, play like an assassin and look for chances to quickly take down squishy carries. Jayce is not durable himself, so avoid diving carelessly in Hammer form into enemies with CC.

Teamfights

Poke repeatedly during the standoff first. Once the enemy is low enough, switch to Hammer form and dive in alongside your team's CC to finish them safely.

⚠️ Common Mistakes

Engaging in Hammer form without poking

Charging in with Hammer form before poking the enemy down is a mistake. Jayce is on the squishy side for a fighter, and a blind dive gets turned on. Set up the kill with long-range Cannon harass first, then use Hammer form to finish.

Jayce Combos

Poke Combo

Deploy the gate from Skill 3 in Cannon form, then fire Skill 1 through it for a fast, high-damage bolt.

3(Cannon)
1(Cannon)

Full Burst

Land the empowered Skill 1 and activate Skill 2. Swap to Hammer with Ult, dive with Skill 1, chain autos, then knock them away with Skill 3.

Jayce Patch History

Jayce
JaycePatch 7.2b
Nerf
Base Stats Base AR: 46 → 37 Losing 9 base AR leaves Jayce noticeably softer against physical damage through the early lane. Standing in Hammer form to win extended trades is a riskier proposition, pushing more of his laning onto poking from Cannon form at range. He also drops faster under minion aggro and jungle ganks, so positioning and recall timing matter more than they used to.
Jayce
JaycePatch 6.3d
Buff
Base Stats Base HP regeneration: 7.5 → 10 Lightning Mana gained per auto attack: increased Total damage: increased Both halves of what keeps Jayce on the lane get topped up. Going from 7.5 to 10 HP regeneration means less standing around recovering after a trade and fewer trips back to base. More mana returned per attack on Lightning lets him keep casting through form swaps without running dry, and with the total damage up as well, the longer an exchange runs the better it goes for him.
