First couple of chests on multiple characters. Not full raid. Chasing sleeper catalyst and emote. I have not done this raid so I am looking for others to learn with me or some super sherpa guides to carry me!
The game creator, astrovir, should send out invites 5-10 minutes before start time. If you don't receive invites, the creator may have left so start inviting each other through xbox/psn/pc on your own.
