The stage of the thermal stone is determined relative to the ambient temperature and each stage emits a fixed temperature:īetween 30° and 10° below ambient temperatureīetween 10° below and 10° above ambient temperatureīetween 10° and 30° above ambient temperature

This insulation is only used for determining the stone's own temperature loss and does not affect the player. The temperature of a heated thermal Stone drops at a rate determined by 120 insulation, which is 1 degree every 5 seconds. Which is simply the midpoint between the ambient temperature and the thermal stone's temperature. If the stone is on the ground instead, the target body temperature is instead given by: Where T_b is the target body temperature, T_a is the ambient temperature, and T_h is the temperature of the thermal stone. With the thermal stone in the inventory, the player's own body will attempt to reach a temperature given by the formula: A Red Hot Thermal Stone can emit enough light to ward off Charlie.Ī Thermal Stone acts as a heat source with an internal temperature between -20° and +90°. The size of the fire affects the maximum charge the stone can attain.

Its purpose is to delay body temperature change, preventing the player from Freezing in the Winter as well as Overheating in Summer ( RoG).Ī Thermal Stone absorbs heat from a fire, regardless of whether it is on the ground, in a Chest, or in the player's inventory. It requires an Alchemy Engine to prototype, and costs 10 Stone, 1 Pickaxe, and 3 Flint to craft. The Thermal Stone, also known as Heat Stone, is a Survival item in Don't Starve.
