Dzemael Darkhold is not part of the main scenario but is a Grand Company quest given by the NPC near the Grand Companies at level 41. The maximum level for this dungeon is 44 and if you are above this then you will be level synced down to 41. Other than completing the quest the main purpose for this dungeon appears to be for leveling, or obtaining better gear. The dungeon is located in Coerthas Central Highlands.
The Dzemael Darkhold was in version 1.0 and shares similar mechanics as the boss fights are the same creatures. The Amdapor Keep dungeon has three sections. We have listed the maps in order of entry.
