Undying Resolve is the name of a permanent buff granted to all Death Knights during their time in The Scarlet Enclave. It allows the death knight to, with the aid of a Val'kyr Battle-maiden, resurrect upon death (with full health) where his or her corpse lays. Note that the Death Knight still suffers a durability penalty, and that he can only be resurrected in such a manner once every ten minutes. If the Death Knight dies more than once in a ten-minute period, then his spirit will spawn at a nearby graveyard, and he will have the choice as usual either to walk to his corpse or to suffer a higher durability loss and ten minutes of Resurrection Sickness.
