Re: Dorian Amulets of Power

It seems that after Patch 5, everyone except Sera and Dorian have 2 Amulet's of Power that they can obtain from quests or the War Table missions, while Sera and Dorian each have only 1.  Note also that you can only obtain Blackwall OR Iron Bull's second Amulet of Power, as they require decisions in-game which are mutually exclusive.

I've not been able to find any other information on legitimate ways to get an Amulet of Power for him.
