Armed with wit, charm, and his signature transforming hammer, Jayce lives to protect his native Piltover. Long before his nation called him a hero, however, he was a promising young inventor. When Piltover commissioned him to study a rare arcane crystal, Jayce discovered it could be used as a vast energy source. Eager to make a name for himself, he began developing a device to harness its power. Word of the crystal's potential reached beyond the borders of Piltover. Viktor, the machine-augmented scientist from Zaun, brought Jayce an offer - together, they could use the crystal to advance his "glorious evolution," a vision of humanity fused with technology. Jayce refused, but the Zaunite had no intention of leaving empty handed. He effortlessly blasted Jayce aside and seized the crystal, incinerating the lab's meager security force as he left for Zaun. Jayce implored the Piltover government to respond, but the officials refused to support an act of aggression. He decided to act alone, realizing that if no one struck back, Piltover would never be safe.
Jayce returned to the lab to prepare for his attack. After intense research, development, and hands-on testing, he emerged with his crowning achievement - the Mercury Hammer. Weapon in hand, Jayce marched to Zaun and began his one-man assault. Viktor's acolytes rushed to stop him, but Jayce smashed them aside, fighting his way into the heart of the lab. Inside, Jayce saw the horrifying brilliance of Viktor's creations, all powered by the energy of the arcane crystal. He realized that his only option was to destroy the power source, but Viktor stood in his way. Though their clash left both scientists heavily wounded, Jayce managed a desperate strike at the crystal. He shattered it and escaped as Viktor's machines erupted in flames. When he returned home, exhausted but victorious, the citizens of Piltover hailed Jayce as a hero. He reveled in the adoration, but knew that his actions had drawn the attention of dangerous enemies. Now devoted to the defense of his people, Jayce is Piltover's best hope for a bright future.
"Trust me: if we're smart, Piltover can stand strong against any threat. Hey, I'm living proof."

Hammer Q's cost reduced. Base damage and ratio increased.
Another niche pick, Jayce has been on the cusp of widespread play for a while now. We’re not touching his poke where he’s already a strong contender, but tuning up Jayce’s ability to follow-up that poke (or create lane presence) with a hammer.
To the face.
Q - To the Skies!
COST : 40/45/50/55/60 mana⇒ 40 mana at all ranks
BASE DAMAGE : 30/70/110/150/190/230⇒ 40/80/120/160/200/240
RATIO : 1.0 bonus attack damage⇒ 1.2 bonus attack damage
In a world without mana potions (and generally less early mana regeneration), we've identified a few champions for some emergency rations, giving early mana boosts until they can get their footing and purchase items to make up the deficit. This also means we can really understand which champions relied on mana potions as a crutch to limp through the early to mid game, and we can give additional love if necessary.
The following champs have +50 base mana and -3 mana scaling (net -1 mana at level 18):
v5.13 R gives its bonuses at the appropriate levels.
"Jayce was actually getting his bonuses a level earlier than intended. He'll still get them, but has to wait for his opponents to have access to their Ultimates before Power-slamming the competition."
R - Mercury Cannon/Hammer
CAN TOUCH THIS : Fixed a bug that gave Jayce his R bonuses at 5/10/15 instead of 6/11/16
v5.11 Transform now has 1 rank, Jayce's spells now have 6.
"For the average player, putting points in R feels like a trap and was rarely satisfying, so we're adding 6 ranks to his spells and giving Jayce his bonuses from Transform when he would have gotten them for free. Below this context are a lot of numbers, but the key things to take away are that Jayce now has very different power spikes relative to other champions, and his signature Shock Blast / Acceleration Gate combo is much stronger, pushing the incentive to take him over similar choices in a dedicated poke/siege strategy."
Q - To The Skies!
BASE DAMAGE : 20/65/110/155/200⇒ 30/70/110/150/190/230
Hyper Charge has been slightly reduced in its total attack damage scaling at later ranks.
"For a guy so strong when it comes to long-range combat, it doesn't make the most sense that he should blow you up in close-quarters without the use of his hammer. Lowering Hyper Charge's late-game shenanigans should keep even the most fed Jayce's out there from getting too unfair. It's also unfair for him to be that good looking, but that's not something we can nerf."
W - Hyper Charge
DAMAGE PER ATTACK : 70/85/100/115/130% total attack damage⇒ 70/80/90/100/110% total attack damage
v3.09By increasing the cooldown on Jayce's Acceleration Gate, we can keep his Shock Blast + Acceleration Gate combo impactful while toning down his poke and disengage potential. In addition, since later in the game not every Shock Blast will be accelerated, we've increased the base speed of the ability to make it better as a standalone skillshot.
Basic missile speed increased to 1450 from 1350 (Accelerated Shock Blast missile speed remains the same)
Cooldown increased to 16 seconds from 14/13/12/11/10
