[b]Bounty: Black Armory Key Mold[/b] [quote]The mold now requires a material known as Glimmering Amethyst. You can find concentration of it in supply caches, public event chests, and strike chests.[/quote] I have ran a few [b]Heroic [/b]Public Events and not one of them, had any Glimmering Amethyst. It seems at the moment, the Glimmering Amethyst is not available through public event chests.
