Check: Whenever you are required to make a Fortitude save or Constitution check to resist the effects of the environment, you can make an Adaptation check instead, using your psychic ability to improve your ability to withstand different environments. Note that Adaptation does not help you against anything that requires a Reflex saving throw or anything other than an environmental condtiion. It does not, for example, protect against falling damage or catching on fire (both of which require Reflex saves).
Action: Adaptation is a free action costing 1 strain per check..
Special: You can’t take 10 or take 20 on Adaptation checks.
