Good lord I think I see ! I never have understood people complaining about wrong forum, but oh okay ancient relic glove ty.

{quoted}

An ancient Shuriman amulet fitted into a glove that focuses his natural talent for arcane abilities. It will never be fully explained because there aren't writers focusing on this shit.

Or anything since the lore was scrapped...
