System: When activated and a Gnosis point spent, this cup actually enhances the alcoholic content of any liquid within it. The liquid must have some alcohol in it (the water-to-wine trick won't work), and the liquid generally doesn't taste very nice, but the alcohol remains overly-potent for as long as the Garou holds the cup. The increase is not drastic -- beer, for example, will increase from one standard drink to about one and a half -- but it does make for a cheap night. As long as the Garou holds the cup anyone can benefit from the effects, making the medicinal dosing of sick Garou an easier task. This is especially useful if the Garou are caught in the freezing cold, making cheap cask wine about as warming as medium-grade whisky.
Spirit: Any spirit servant of the Incarna Grain can be bound into this cup.
