Patch 1.9 brings the first Instanced Dungeon to Stardust. The Catacombs of Exar Kun. A group of 10 players is necessary in order to complete the dungeon. In order to enter, simply travel with your group to the Temple of Exar Kun on Yavin 4, and interact with the brazier along the northern wall of the Temple. Select an instance to enter, if the instance is not already occupied your group will be transported inside.
Once inside the instance there are only two ways out. Death, or finishing the instance. You have 60 minutes to complete the dungeon before you are kicked out so move quickly!
