Healthy Flush (3.5e Maneuver)

Even though you are wounded, your blood is already clotting and rebuilding your body.

When you use this maneuver you gain fast healing 10 for 1 minute. If you are brought below -10, you continue to gain fast healing and still count as a creature, not a corpse. If this healing would bring you back over -10 hp before the duration ends, you do not die. At any time during the duration as a standard action you can regenerate any lost limbs, which burst back good as new. This ends the maneuver.

You can only use this maneuver once per encounter, or once per minute.
