The Bracelet

When Darkstalker is attacked, he creates a bracelet that can't come off of him and cannot be further enchanted, and this protects him from many of the attacks, however it breaks into several pieces and thus most of it falls off, making it lose it's power. The bracelet's remains were scattered across the continents afterward. If they were to ever re-connect together, Darkstalker would come back to life.
