Mask of the Branded

Appearance
The mask only has one eye hole and is pure white. The single eye hole has a black circle with a line that runs straight down the mask

Powers
The mask once a day can be used to summon a giant shadowy great sword that does not have a weight. The weapon also uses finesse. It deals 3d8+4 slashing damage and the user takes an unknown side effect as the mask has yet to be used.

Location/Acquisition
Leo found the mask in a hidden room inside of a dungeon that the deep ones were using as a storage facility. He managed to see it with a bull shit roll.
