Hearths

Hearths are Warmth specialization buildings that reduce Hostility and cannot be built close to other Hearths. Every few minutes, workers take breaks and return to a nearby Hearth to eat and rest. During a break, they consume at least one item of food and try to fulfill all their needs. If a villager has multiple needs tied to complex food, they will consume more than one meal.

If the fire goes out all villagers will lose 20 Resolve. To keep up the flame, a Firekeeper and a steady supply of Fuel are needed. You can decide which type of fuel will be burned in the Hearth by selecting it and using the checkboxes next to the fuel types in the selection UI.

Hearths allow up to 3 additional fuel to be sacrificed to gain additional bonuses:

40 Wood per minute can be sacrificed to give -50 Hostility
20 Coal per minute can be sacrificed to give -80 Hostility
20 Sea Marrow per minute can be sacrificed to give +25% Glade Event working speed
15 Oil per minute can be sacrificed to give +25% global production speed
