The map for this dungeon has changed. There is no longer the upper area with the Sarcophagus'. Mobs tend to stay in the level 100-200 range. It is obviously not been through a balance pass as mobs like the Coerced Aegiscian's seem fairly overpowered for their level. The Reanimated Seraphs also tend to hit rather hard. You will want Death Magic Protection as well as Free Will depending on the fight. Seems as if the only reason to run this is a SB of Etheralize.
