LFG Gaming for Archon Forge
The new Court of Oryx in Destiny: Rise of Iron is the Archon’s Forge. It works very similar and you have to bring offerings this time around to enter the 3 tier arena.
If you don’t have someone to join it can get frustrating because your wasting your offerings. Good things there’s LFG sites where you can join other players or give a shout out for something you want some backup.
