Step 1: If you see a message "Diablo 2 Server is shutting down in 5 mins" or some shit like that get a friend in there and give him all your items.
Step 2: Have him leave the game and just sit there until server closes and bamn, rolled back.
Step 3: Make your friend give you all the duped items !!ON A DIFFERENT CHAR THEN THEY CAME FROM!!
Step 4: Perm em and go trade!
I haven't done this myself. Got it from EoN. I'm going to try it with my friend, though.
