Hey there, old pinnacle/ritual weapons don't count, and as for newer weapons, they do get added to the pool of accepted weapons eventually but the latest will not have been added. So, The oldest gambit weapons will count, if you've still got them, like Bygones, Trust, etc. Bad Omens was reissued and counts. Malfeasance definitely counts too. Gambit Prime weapons are fine. Night Watch, Gnawing Hunger, etc. Out of the more recent weapons, there's Borrowed Time, Servant Leader, Trinary System, Bottom Dollar, Crowd Pleaser, those are all valid. But, Dead Weight (Haunted), Yesteryear (Plunder) and Albruna-D (Seraph) have not yet been added.
