Dragrimmar Chest

A Dragrimmar Chest will spawn after defeating Remnant of Antiquities in the final level of the Sepulchre of Dragrimmar dungeon. Each player in the party may open the chest and will receive one item from the drop list in normal mode (two in hard mode). After the chest has been opened by every player, a countdown timer will begin and players will be transported outside the dungeon after three minutes.
