So i was grinding the Lord of Wolves Catalyst in The Whisper (heroic) mission in the thrall room to make it easier and then when i got the triumph and catalyst unlock for the LoW i also got the black talon triumph so i thought "huh maybe its just general kills" but when i checked the black talon to apply the catalyst, it wasn't complete. No clue why but thought i'd make a little post to let bungo know
