I'm writing a fanfic about Kayle and Morgana and I want to have Demacia's strongest metal in it, and when Demacia and metal are brought up together, the first thing I think of is petricite, but I'm not sure if petricites Demacia's strongest metal. It probably is against mages like Morgana but if its not the strongest metal, does anyone have any idea what is???
EDIT: Prior to this, I hadn't bothered to look into the lore of Demacia, I just skimmed the Demacia page and thought petricite was a metal. That is my bad. Still looking for Demacia's strongest metal tho.
