Daggerfall Unity: Regenerate HealthEdit
Regenerate Health is one of the special advantages a player class can have. It causes the player to gain 15 health per in-game hour, regardless of whether the player is resting.
Rapid Healing can be chosen for "general" (all circumstances), "in light" (meaning outdoors from 6 AM to 6 PM only), "in darkness" (meaning all circumstances that are not in light), and "while immersed in water."
