Fireplace

A fireplace is a construction that can be built on a floor inside a cabin. It requires 35 stones to build. A fireplace is required to create a heated room, which is required for smoking meat. Fireplaces in village saunas or inns will re-light when they burn out. When wood stops burning in a fireplace, however, the embers continue to provide heat (meaning it can still be used to cook food). This keeps your cabin heated in the winter for longer using less wood. It requires 6 firewood to get started. You can also treat your frostbites near the fireplace providing heat.

FYI:  All garbage (like rotten hide or sand mushroom) can be burned. Also good for burning inferior or poor boards.
