Duplicating items"Duping":

To dupe an item, first drop the item you want to dupe on the ground. Then walk a small distance away(half the screen is good for the first time). Then walk back and pick up the item. The exact moment you pick up the item, click a potion or scroll in your belt. The potion or scroll's name should change to the desired object. Then drop the converted item on the ground and your done. Be warned, if you have 2 of a duped item on the ground at once, one or both will be destroyed.
