Rapid Heal is a Prayer that halves the interval at which the user's Life points are restored from 6 seconds to 3 seconds per heal outside of combat.
Rapid Heal does not drain the user's prayer points quickly, but can not take effect in combat. This limits its use to out of combat. Using healing Abilities or a healing familiar such as a Bunyip is recommended instead for players in combat.
This prayer does not increase the healing from Rest or Food
Training: turn it on the moment you start training, along with various prayer boosting equipment, such as an Amulet of Glory. This may provide you with 300+ life points, depending on how long you stay in the area, your prayer level, and whether or not you use other prayers.
