Moon Shell

The Moon Shell is a hardmode item which can be crafted using the Tinkerer's Workshop. It has the combined effects of the Moon Charm and the Neptune's Shell hardmode accessories. Wearing it will turn the player into a Werewolf every night, and a Merfolk when entering water, regardless of the time of day. If it is night and you enter the water, the Werewolf buff will be removed and replaced with the Merfolk buff until you exit the water.
