There is an agnostic version of this dungeon available to players level 10 through 95.
The aggro range for mobs is quite large, so keep your distance.
Many of the trash mobs have a frontal or AoE that they use almost immediately upon pull, so keep your distance, use stoneskins, have wards, or throw up AoE blockers.
Will engage almost immediately after you take a step inside the zone
If on the quest Rage Against the War Machine, pause near the end of the long hallway before you reach the Great Hall, so that you can listen the discussion which will update the quest.
If on the quest A Prince Amongst Kromzeks, clear the Trophy Room and knock over the statue at ( -460, 119, 436 ) Copy/waypoint -460, 119, 436 to distract the guards BEFORE taking on Halkon Tormax.
