A creature with fast healing has the ability to regain hit points at an exceptional rate. Except for what is noted here, fast healing is like natural healing.
At the beginning of each of the creature’s turns, it heals a certain number of hit points (defined in its description).
Unlike regeneration, fast healing does not allow a creature to regrow lost body parts. Unless otherwise stated, it does not allow lost body parts to be reattached.
A creature that has taken both nonlethal and lethal damage heals the nonlethal damage first.
Fast healing does not restore hit points lost from starvation, thirst, or suffocation.
