Riot Games can't stop with the Hextech skins. After Amumu in last September, a new League of Legends champion is joining the Hextech craft industry. This is Swain, the Noxian Grand General.
As usual, this new skin will be available through Hextech craftsmanship and you can obtain it with 10 rare gems. Currently tested on the PBE, it should be implemented into the game alongside patch 9.24.
