Hacked Items

In D2 you can buy unidentified items such as Windforce. To the best of my knowledge an unid item cannot be a dupe.

However, Maple is a lot more money-oriented, so the hackers can sell their 50 int saunas for $$$. I know a guy who seriously considered spending 7,000 dollars to buy all-perfect gear for his character. Two guesses where those perfect items would come from.

UnID'ed items can be duped. The only difference between UnID'ed and ID'ed items is whether the ID'ed tag is a 0 or a 1. Otherwise, the item will have the exact same stats. If you were to dupe an UnID'ed item, and then ID both of them, they would be exactly the same. Stats aren't rolled upon IDing but at the exact moment the item is created at drop. Windforces suck, by the way.
