With this mutation, the character can raise or lower the temperature of a visible object within a range of 90 feet. The specific form of the power must be determined at character generation (50% heat, 50% cold). The mental nature of this mutation requires concentration, and the effect is a graduated level of damage equaling 1d6 per round. The maximum amount of damage that can be dealt is 10d6 per round. The ML will decide when an object or being combusts or freezes completely.
