Hand of Old Blood

The hand of old blood allows the wielder to reopen any old wounds on a person, even wounds that have long since healed. The wielder cannot increase the severity of wounds, but opening every wound an immortal has ever taken in a lifetime of violence is usually sufficient to weaken even  an immortal. It is similar to the hand of blood, but is more specific, and can be used over a distance without the aid of a weapon such as Aben-dul.
