Endothermic mold feeds on warmth, siphoning heat from anything around it. A patch of endothermic mold is red-brown in color and 5 feet in diameter, and the temperature is always cold in a 30- foot radius around it. Living creatures within 5 feet take 3d6 points of nonlethal cold
damage. Fire brought within 5 feet of the mold causes it to instantly double in size.
