 Adaptation (Wis)
You can adapt your body to survive in hostile environments.
Reqirements: Psychometabolism feat
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 condition. It does not, for example, protect against falling damage or catching on fire (both of which require Reflex saves).
Special: You can’t take 10 or take 20 on Adaptation checks.
Time: Adaptation is a free action.
Strain: 1 per check.
