Does anyone know if these can be looted from perfect performance of Sacraments? I've completed several Sacraments (including all optional objectives, i.e. a "perfect" run) but don't think I've gotten a motif from it yet. Does this mean they are exclusive only to bosses and chests?
I ask because perfect completion of TG heists awards motifs. It very well could be that it's simply different for Assassin's League.
