It's that time again! New skins have been officially released and will be available upon patching. As per every other champion since Xin Zhao, Jarvan IV is launching with two custom skins; Commando Jarvan and Dragon Slayer Jarvan IV. As for other champions, Loch Ness Cho'Gath is splashing onto the scene and Anivia is getting the Hextech treatment.
It looks like Dragonslayer Jarvan is going to run you 975 RP and Commando will cost you 520. I'd be hard pressed to imagine either the Anivia or Cho'Gath skin costing you less than 975 as well.
