Elder Scrolls IV: Oblivion Tips & Tricks

To duplicate almost any item, first get two or more magic scrolls of the same type, depending on how many duplicate items you want to create. Be aware that this trick wont work with stolen scrolls. Go to your inventory and select the scroll twice, then drop the item that you wish to duplicate from your inventory. When you exit your inventory and return to the game you'll find your duplicate items on the ground.
