Dungeon Journal

With the Aegis of Aggramar socketed back into its cradle, Domatrax leads an onslaught of demons to destroy the relic.


Upon reaching 90% and 50% health, the Fel Lord opens up additonal portals to allow greater numbers of the Legion's soldiers to pour into the tomb. The Aegis of Aggramar provides protection against the Legion's attacks, but if drained of all its energy, this aura will fall. On Mythic difficulty, if the Fel Portal Guardians are not destroyed within a specific time, an overfiend emerges.
