===Healing===
After taking damage, you can recover hit points through natural healing or through medical healing. In any case, you can’t regain hit points past your full normal hit point total.

'''Natural Healing:''' With a full night’s rest (8 hours of sleep or more), you recover 1 hit point per Health Rank. Any significant interruption during your rest prevents you from healing that night.

If you undergo complete bed rest for an entire day and night, you recover twice your Health Rank in hit points. 

'''Medical Healing:''' Various herbs, medication, heal check can restore hit points.

'''Healing Limits:''' You can never recover more hit points than you lost.

'''Healing Ability Damage:''' Ability damage is temporary, just as hit point damage is. Ability damage returns at the rate of 1 point per night of rest (8 hours) for each affected ability score. Complete bed rest restores 2 points per day (24 hours) for each affected ability score.
