Dungeon MasterG 50

This achievement is unlocked once you complete 25 epic dungeons. This will come naturally as you use the Dungeon/Skirmish Que System to join other players to run through the various dungeons once you hit level 70. Keep in mind that only a select few dungeons will be available to you once you reach 70. Besides being level 70 epic dungeons also require that you have an item level of 1600 to enter the first tier of dungeons, then 2000, and finally a 2500 item level for the last dungeon currently in the game called Demogorgon.
