Hit points reflect both the actual physical ability of the character to withstand damage—as indicated by Constitution bonuses—and a commensurate increase in such areas as skill in combat and similar life-or-death situations, the “sixth sense” which warns the individual of some otherwise unforeseen events, sheer luck, and the fantastic provisions of magical protections and/or divine protection.
When a character loses hit points in combat or to some other attack form (other than being drained of life energy levels), there are a number of different means by which such points can be restored. For example, clerics can restore such losses by means of curative spells. Commonly, it is necessary to resort to the passage of time, however, to restore many characters to full hit point strength.
For game purposes, it is absolutely necessary that the character rest in order to recuperate, i.e. any combat, spell using, or similar activity does not constitute rest, so no hit points can be regained.
For each day of full rest, a character will regain 1 hit point per level or hit dice, up to and including 7 days. However a character with a penalty for poor Constitution must deduct, weekly, the penalty score from his or her days of healing.
After the first week of continuous rest, characters with a bonus for high Constitution add the bonus score to the number of hit points they recover due to resting. (i.e. Each day will heal their level plus Constitution modifier.)
Regardless of the number of hit points a creature has, 4 weeks of continuous rest will restore any creature to full strength.
When any creature is brought to 0 hit points or below, it immediately becomes unconscious.
At the end of each round (the end of segment 10) after the round the creature became unconscious, the creature will automatically lose 1 (negative value) hit point from bleeding, shock, convulsions, non-respiration, and similar causes. At -10 hit points a creature will die.
Automatic hit point loss is halted if any creature spends one round administering non-magical aid (binding wounds, starting respiration, etc.). Otherwise, any magical healing will also halt automatic hit point loss.
Recovery
Scarring. If any creature reaches a state of -6 or greater negative points before being revived, this could indicate scarring or the loss of some member.
