The morph is adapted for extreme cold and has difficulty dissipating body heat in temperatures tolerated by normal transhumans. When exposed to vacuum or temperatures above 5 C for more than 10 minutes, the character suffers a −10 modifier to all actions. At 10 C, increase the modifier to −20. At temperatures above 25 C, the character may suffer 1d10 DV per hour exposed from overheating, at the gamemaster's discretion. These effects can be nullified by wearing a vacsuit, the application of some sort of cooling system, or returning to a suitably cold environment.
