This year's League of Legends World Championship will be commemorated with the limited-release "Championship" skin for Jarvan IV.
Every year Riot Games releases a special skin in the League to celebrate the game's World Championship. The tradition started in 2012 when Riot released a Championship skin for Riven during the game's second World Championship. Championship skins have since been released for Thresh, Shyvana, Kalista, Zed, Ashe, Kha'Zix, Ryze, and most recently LeBlanc.
Championship Jarvan IV will leverage the thematic elements of the costume lineup, which traditionally includes a blue, gold and silver color scheme, as well as accessories and designs with an overall esports focus.
For example, Jarvan's ultimate ability, Cataclysm (R), will summon a wall of silver and blue dragons around him when used. Also, Jarvan's costume return to base animation resembles a sapphire and silver throne, similar to the colors of the Summoner Cup awarded to the team that won the World League Championship.
Jarvan IV will be the first champion on the League roster to earn both the Championship and Glorious skins, and this skin will be awarded to players who reach Gold rank or higher in a given competitive season. A Glorious skin skin has been released for Gold or higher players at the end of the 2011 ranked League season. Now 10 years later, another Jarvan skin look will mark the end of the 2021 pro season.
Riot has yet to announce a release date for Championship Jarvan. Judging by history, though, Championship skins are almost always released in the last week of September, just when the Worlds start.
