Neverwinter

Like many other campaigns in Neverwinter, this will not be complete until you have purchased all the boons associated with it, not just the story portions. The boons cost 175 Omens each, so exactly 4 weeks after maxing the amount of Omens you can earn in one week. This should take roughly 7-8 weeks total after completing the story sections. Faster if you would care to buy the Vistani Wanderer Companion. It increases the amount of Barovian currency that you receive when completing tasks.

The achievement also didn't pop for me until I logged out then back in again. Good Luck.
