Planar adaptation grants you immunity to the harmful environmental effects of a particular plane of existence, including such hazards as toxicity, extreme temperatures, and lack of air. Additionally, you gain energy resistance 20 to a single energy type prevalent on that plane (choose one if more than one type is equally prevalent). Planar adaptation has no effect when cast upon your native plane.
