Living Furnace

--- Forged in a sun's flames, your body is a living furnace that releases an abundance of thermal energy. You become inured to high temperatures, and your body sheds a pleasant heat that can stave off the cold. You gain resistance 4 to fire. You and creatures within 20 feet of you treat environmental cold effects as if they were one step less extreme (incredible cold becomes extreme, extreme cold becomes severe, and so on).
