Masks

Masks are items the Hero can wear in Fossil Fighters and Fossil Fighters: Champions. While they are largely cosmetic, some are required to visit certain areas or activate events, and in Fossil Fighters: Champions, certain masks have special effects that the player can use to their advantage while digging. The Hero's mask can be changed or removed at the Fossil Guild's Mask Salon.
