Item generation? No problem!

pretty sure being able to generate any item in the data is quite profitable.
although, scrolling gear is a good way of hiding the evidence. Nexon wouldn't suspect a thing.
"109254135 attack gear? Dang, they got lucky!"

There's a limit with clean items once it becomes common place it isn't that great. Scrolling end game gear is as feasible as you can get especially since positive chaos aren't available en masse at all.

Besides, it's not like nexon will wipe at least not immediately if dupes are any indication. Not sure how well they can track generated items, but it may or may not be easier than duped items.
