Thought I would share this - I'm sure there could be an even easier way but as this mission is used a lot to get Eris Morn Bounties done I thought it was worth mentioning.
-
I just load up dark beyond level 9 with a checkpoint at the sealed gate. I do all my eris bounties there.
-
Go to the first moon mission "We've woken the Hive" and wait for them to rush you from the door. You don't need a fancy helmet either.
-
I do many of these types of bounties on The Wakening, lvl 24, in the area where the cursed thrall just keep on coming. Run a wax idol and earn lots of glimmer at the same time.
