DS Name: Toma's Spirits
A bottle of spirits received from an explorer.
During the Rainbow Shell sidequest, Toma in 600 A.D. instructs the party to, if he should ever perish or fail in finding the Rainbow Shell, pour his drink on his grave. Doing so at the West Cape revives his ghost, who informs the party that the Rainbow Shell is located within the Giant's Claw.
Translation: Toma's sake
