Jayce Talis is a brilliant inventor who, along with his friend Viktor, made the first great discoveries in the field of hextech. Celebrated across Piltover, he tries to live up to his reputation as "the Man of Progress," but often struggles with the expectations placed upon him. Because of this, Jayce has begun to see the ways in which his invention has furthered the division between Piltover and Zaun—and armed with his hextech hammer, he stands ready to defend tomorrow.
Jayce was released on July 3, 2012. Players could purchase them with Riot Points or Blue Essence as soon as it dropped in-game.
Jayce is primarily played in the Jungle lane and falls under the Fighter class. However, they can also be effective in the Middle depending on team composition and matchups. The champion's kit and playstyle make them most suited for it, where they can maximize their impact throughout the game.
Currently, there are 11 Jayce Skins available in the game. This includes all cosmetic variants released since their launch, the base skin is not included.
Jayce costs 2,400 Blue Essence or 880 Riot Points. You can purchase them from the in-game store using either currency. Blue Essence is earned through the battle pass and disenchanting champion shards, while Riot Points require real money to obtain.
