I have been going through Skyreach dungeon multiple times in order to get the Pristine Plumage flight gadget.
For anyone like me that never got that object when clearing Skyreach either in a group or in failed solo attempts - this is how I solo'd the Pristine Plumage.
I got an invisibility potion from my garrison’s Alchemy building follower.
Cleared the first two bad guys, got as close as I could to the next mob without attracting combat. Ensured I had a VoidLord (as a destro Warlock) alongside. Took the potion and ran as directly to the feather as I could and managed to obtain the feather before I was attacked by the local bad guys.
