Stellar Equilibrium
Source
Armory pg. 100
You can draw energy from your connection to the cosmos to regulate your internal temperature and even your physiology. Also long as your solar armor is active, you can exist comfortably in conditions between –50° and 170° F without needing to attempt Fortitude saves, and you do not need to eat or drink to survive.
When you are attuned or fully attuned, you ignore the environmental effects of being in a vacuum and receive a +4 bonus to all saving throws against diseases and poisons.
