This Jayce Guide for Top Lane is by Rhux, a Challenger-level top laner. Jayce is an extremely versatile champion who can do massive poke damage, as well as high melee burst damage with a gap closer. He can be a difficult, but rewarding champion to play depending on the player's skill level.
Jayce is one of the few hybrid champions,reason why he is hybrid is because of his ranged/melee swaps,not the 50/50 magic/physical damage.He can be built as tanky bruiser with Randuins and Trinity or a well AD carry with Infinity Edge/Bloodthirster and Last Whisper.I believe he must be played mainly top lane and build tanky on early game with Randuins and Trinity as his core items and in mid game starting to shift into what is needed to finish the game.Whether it is being more beefy and getting additional Magic resist via Maw of Malmortius or more sustain through Bloodthirster or maybe more sustained damage from Wit's End.
His role is to be anti ad carry,his kit is perfect for that.He has a jump Q(melee form) and E percentage damage(melee form) and on top of that he can switch into ranged form where he can finish off the running target with his Q or max attack speed ability W.
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." - Jayce
