From Reddit LINK:

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. (See below edit on how to check number of tributes. 18 times I believe is needed for the juju. 50 times will unlock everything)

Once you've done it your desired amount of times, switch back to your primary character. Place another tribute to complete the quest, then enter the hall. You should be able to do everything inside the hall and unlock the JuJu.

EDIT: There are a few questions that keep coming up that the post doesn't explicitly answer.

To check how many tributes you've gotten, go to your menu -> Triumphs -> Destinations -> Minor -> Tribute Hall. It's the first Triumph.

Regarding steps 3 & 4, yes accept the quest from the emperor that requires you to place three triumphs. That's what "further the quest" meant. DON'T PLACE THE FIRST TRIUMPH BY THE DOOR ON YOUR MAIN CHARACTER THAT HAS THE QUEST.

Once you've gotten all the tributes you want, yes, you have to switch back to your main character who has the quest to get Bad Juju. Since the main character has the quest, the main character does the next step.
