He's obviously trying to cheat the staff to get a DF, stuff like DF doesn't appear that way in your bank, i have seen bugs like a normal agito turned into an original agito and since then i haven't seen that kind of bugs, just "????" or changing back to the original item (like combining an Ophelie Seize and Heaven Punisher to make a Mille Marteaux, then turning back to Heaven Punisher or OS), but that was 3 years ago, and items doesn't appear that way, specially such a good item with stats, you might have obtain an item from some kind of bug, but not a DF, maybe a Surya lvl 0 like what happened the other day, something that is considered a bug
