I've done the entire Duality dungeon with a full set of the legendary fully rekindled (Spark of Resilience) armor set and no progress was given to the triumph In Candescent. The class item is masterworked but the rest of the armor isn't yet since I'm not happy with the stats yet. Maybe it's not progressing because it's not masterworked? I will be doing some raids tonight if my crew gets on so I can repost or update with those results as well. I'm not using an exotic armor piece as mentioned it is the full set. It's the last triumph my wife and I need so any reply would be appreciated :)
