New Skin concept
I've created a host of new material that can be implemented in the game as a new patch ( https://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/Eal50gAL-nasu-010-concepts-gallery ), but it would not be complete without skins.
Power bound skin line The idea is to have the champions encased in obsidian (black stone ) and pulsing with colored energy runes.
Am not an artist so unfortunately I don't have any drawings but if someone else is willing comment below and we can get to work
