How do you do the duplication cheat on Oblivion?

Answer 1

It is all dependent on scrolls. If you have 10 Incinerate scrolls (or any other multiple scroll). Swing your weapon, mid-swing, open your inventory, select your 10 scrolls (mainly it needs to be any number over 1), and drop the item you want to duplicate (it works best if you only have one of the item, so if you have more than one, drop all but one before you start the process). When you exit your inventory, you will have dropped 10 of the item (or whatever other number of scrolls you have). Enjoy!

Answer 2

first go to a scroll that you have at least two of (or more) then go to an item that is not equipped (that you're not wearing/using) and drop it. when you go back to the game, you will have dropped more than on. an example is click on a scroll you have more than one of, next you drop a steel helmet. when you get off of your journal and go back to the game, you will have dropped two or more. (i did this on a playstation3 ).
