There's a way to exploit tributes. I've taken this from a Reddit post outlining the steps. Is it a bannable offense to use? If you have already opened the doors to the Tribute Hall, you're out of luck. If you haven't yet, this is how you can get infinite, free triumphs for Bad Juju, it's catalyst, and even the exotic emote. On one character, start the Invitation from the Emperor quest by going to the barge on Nessus and opening the chest next to Werner. On the same character, go to the Tribute Hall, and approach the emperor statue. Pick one of his bounties and complete it. On the same character, return to the Tribute Hall, and approach the emperor statue again to further the quest. At this point, the emperor will give you a tribute to deposit at the door. It is signified by the diamond indicator. DO NOT PLACE THE TRIBUTE. Switch characters. On your second character, load into the Tribute Hall. On your second character, place the tribute by the door. On your second character, go to orbit. On your second character, repeat steps 6-8 as desired.
