What They Do

AD poke-and-burst bully. In Top lane, he uses his range to harass you with in Cannon form, then swaps to Hammer form to execute you with a high-damage leap and knockback. He lacks a traditional ultimate but has twice the abilities early on.

Abilities (What to Watch For)

Ability	What You'll See	What It Means For You
	Small burst of speed and ghosting when he switches forms	makes him hard to catch or kite right after he swaps weapons. Don't expect to easily land skillshots when he changes forms.
	A blue orb (Cannon) or a leaping hammer strike (Hammer)	Cannon is his main poke; Hammer is a leap that slows. If he hits the Cannon version, he's looking to all-in you immediately.
	Electrical aura (Hammer) or three fast attacks (Cannon)	Cannon gives him max attack speed for 3 hits—this is how he wins short trades. Hammer gives him mana back, so he'll hit minions with it to sustain.
	A glowing gate (Cannon) or a hammer swing that knocks you back (Hammer)	Cannon accelerates his for massive damage. Hammer is his only peel; if he uses it to disengage, he is vulnerable for nearly 20 seconds.
	Weapon transformation animation	lets him swap forms. Cannon-to-Hammer gives him bonus resistances and magic damage on his next hit. Hammer-to-Cannon shreds your armor and MR on his next hit.

Respect

!
The Accelerated Shock Blast→The + combo in Cannon form deals massive AoE damage from long range. In the long Top lane, he will use this from the bushes to chunk you while you try to farm.
!
Level 1-3 Power Spike→Because is available at level 1, he effectively has 6 abilities by level 3 while you only have 3. He can easily force a Flash or a kill if you try to trade early.
!
Hammer Form Execute→If you are below 40% HP, a Top Jayce will swap to Hammer and use to gap-close, then to deal % max health magic damage to finish you off.
!
Bush Control→Top Jayce uses the three lane bushes to drop minion aggro after hitting you with a ranged auto or . If you lose vision, you can't trade back.

Punish

+
Hammer is on cooldown→This is his only way to get you off him. If he uses it to trade or misses it, all-in him immediately. Without it, he is a squishy immobile target in the long lane.
+
Early Mana Depletion→Jayce's + combo is extremely expensive. If he spams it and misses, he will be OOM (out of mana) and forced to use Hammer on minions to recover, making him an easy target.
+
Form Swap Cooldown→After he uses , there is a 6-second window where he is stuck in that form. If he swaps to Cannon to poke, he can't go Hammer to peel for himself if you jump on him.
+
Missed Cannon →A huge portion of his threat is tied to his gated . If he fires it and misses, you have a roughly 10-second window to contest the wave while his main damage tool is down.

Laning Tips

•Stand behind your melee minions; they have a larger hitbox to block his Cannon than casters do.
•Rush Plated Steelcaps. Almost all of Jayce's trading damage is physical, and the move speed helps you dodge the + combo.
•Bait his Hammer knockback before using your gap-closer. If you jump in, get knocked back, and then use your dash, he can't escape.
•Keep the wave near your tower. Jayce is a lane bully who hates being overextended because he has no built-in dash to escape ganks, only the move speed.
•If he stays in Hammer form, he is looking to restore mana with or all-in you. If he stays in Cannon, he wants to poke.
•Watch his mana bar. If it's below 25%, he literally cannot perform his full Cannon + combo.

Teamfight Warning

⚠He will sit in the Fog of War to fire accelerated s before a fight. Ward the jungle flanks to avoid being chunked to 50% HP before the fight starts.
⚠A Top Jayce often functions as a secondary assassin. Watch for him to use (Cannon) to speed up his team and then dive your backline in Hammer form.
⚠If he is splitting, don't send a squishy alone to stop him. His (Cannon) melts towers, and he can 1v1 most non-tanks easily.
⚠In neutral objective fights (Baron/Dragon), his (Cannon) gate is a massive team-wide buff. Don't let his team engage while they have that move speed.
⚠Save CC for when he enters Hammer form. He has to get into melee range to use and , making him vulnerable to being focused down.
