For Night Fae covenant, upgraded Queen’s Conservatory to highest (5th) level. As expected, saw epic (purple) spirit rewards offered in Ve’nari’s weekly quests; as per text color displayed when mouse over quest reward icon. BUT, when I turn in the quests, the spirits rewarded are only rare (blue). I don’t want to do her quests until this is fixed. Because I’m not aware of any other source for divine (purple) spirits, this is SO DISAPPOINTING.
I have seen other reports of this in bug reports. You may want to check it out and contribute your experience in that forum instead. Queen's Conservatory Spirits Bug - #13 by Kipedget-proudmoore
