The '''Thermal Bar''' was a removed resource system originally added in 2.0. The Thermal Bar added a "temperature mechanic" of sorts to the mod, where going too long without being near heat sources or eating hot foods would cause the player to freeze to death, slowly taking damage until they warmed up. This mechanic was removed shortly after its implementation due to unpopularity, but it was repurposed into the similar Vitality bar, covered below.
