Boss Mask

Boss Masks are vanity items dropped by most of the bosses added by Thorium. They are worn in the social head slot, like vanilla masks. Each boss has a 10% chance to drop its own mask.

Trivia

 * Patch Werk, Corpse Bloom, and the Illusionist do not drop a mask.
 * Defeating The Primordials grants a chance for each mask to drop individually, which means more than 1 of the masks may drop at the same time. This also applies for the Treasure Bag.
