A couple of months ago, I did write out everything you’ll need / obtain, naturally to unlocking the Nightborne, naturally:
I actually followed this guide, twice. Once, for myself, and the second time was for the hubby. Doing it on his account (on his computer and not mine) was only slightly different. When I did mine, it was all in one sitting. There was a break/pause with the Hubby, so I had to make sure I mana fed them, as well. I just followed everything the guide told me. It lists all of the quests required and what’s optional.
EDIT: There’s actually a quest still listed as “required”, when it’s not, and I mention that, too.
