I saw that ability in WoWhead, and it’s apparently still a thing. Makes players you revive come back with 100% health and 60 (?) mana, and gives the DK themselves the ability to revive once after dying. I can’t find it anywhere tho, did it get removed at some point and WoWhead just didn’t update it?
