Revivification

Revivification is the ability to restore life to a dead person. The possibility of resurrection is reduced by the number of hours the person has been dead. If the person is restored to life with any success, they will remain in shock for quite a while like not fully being there.
Revivification only keeps the victim's spirit from departing. It does not heal injuries; this requires further treatment, particularly brain and heart damage if those and other organs are unable to get enough oxygenated blood.
