The three recovery transactions the game actually offers: a watchful field rest, a cleared-site camp, and a paid full night.
Recovery is time-based. A one-hour watchful rest and a six-hour camp restore
1 HP per character level, modified by physiology, feats, and augments. A paid
eight-hour night in safe lodging fully restores biological HP and gene-psion
talent pools, clears Fold pressure to its permanent floor, and resets daily
abilities. Synthetic bodies require repair rather than sleep.
Paid sheltered lodging supplies a warm environment. An ordinary cleared
site or watchful field rest does not establish warmth for cold injuries.
