The First expansion to DELVE, Feast and Famine introduces the Hunger mechanics from UMBRA to your dwarvish holds. To stave off starvation, you'll have to use the new farming rooms like the Forge-Bee Apiary, Mushroom Gardens, or Cave Goat Milking Sheds. Crops can then be processed to create special benefits like STR bonuses, unique adventurers, new golems, and more. Feast and Famine also introduces Cave Goats, horrific dwellers of the depths that dwarves keep for their famously magical cheese. There are 6 species to find, each with their own unique benefits.
