The Monolith Dungeon requires the player to have the Sorcerer DLC which can be purchased In the LOA Shop. This is a much exciting class with multiple summons to fight along side you.
Unless you have a group to venture into this Dungeon, you might want to be a master at your class, as these mobs tend to Heal often.
