Mask of gu

The Mask of gu is a part of the cosmetic Gu outfit from Player-owned ports. It is obtained from a Gift of Gu chest after giving a donation to The Tengu after completing his final clue voyage.

Each chest donation has a chance to provide a parcel with a random reward, but a donation of 25,000 chimes will guarantee a parcel containing one of the Gu cosmetic items that the player does not already own.
