Members of the Protector class are granted the power of regeneration. Under normal circumstances, this power allows an injured protector to regain one hit point every hour. This power also gives the Protector a +4 to any save or checks versus scarring or infection. Aside from injuries, the regenerative power also allows the Protector to regenerate amputated limbs and knit broken bones. The innate power Regeneration also functions in this same manner.
Should a character with Regeneration fall to negative hit points, a successful Body-Mind-Spirit check indicates that the regenerative power is sufficient to stabilize the character's health. Thus, a mortally wounded Protector will not recover without medical intervention, but neither will she bleed to death.
Constructs also have a variation of the Regeneration power. The Complete Regeneration power for Constructs heals one structural point per day. Note that ALL Constructs are assumed to have this ability, including enemy Constructs that characters battle against from the lowliest armour Drone the nearly unkillable War Master. Thus, when battle a Construct, it is best to make sure it is completely destroyed or it will rise up and return to full health in a matter of days or weeks.
