Hungersbane

Technically poisonous, Hungersbane is the sacred drink of Worgoth, the Wolf at the Door. This unpleasant-tasting mixture of Mushrooms, alcohol (it doesn't matter which type), and blood, turns off all but the vital parts of the digestive system, meaning the imbiber does not need to eat so much. It is used in the lower levels of the city, when food is particularly scarce.
