Duplicate in Elder Scrolls 4 Oblivion

In order to duplicate, you must have more than one of the same scroll. What you do is, click on the scroll a few times(On your inventory, not your spells)- I think 5 is the max times you need to press the button, but if you have less than 5 scrolls, just press it by however many scrolls there are(2 times for 2, 3 times for 3, etc.), and then drop the item you want duplicated. The item cannot be stolen, but the scrolls can be. Also, unique items- that is to say, items that have icons that are unique, not enchanted things that have normal icons(I.E. the Deciever's Finery can be duped, because it's icon is just a Black and Burgundy outfits, but the Boots of Bloody Bounding cannot be duped, because their icon is unique)- cannot be duplicated. Also, be warned- duplicating too many of the same item at the same time will slow and probably crash your game. I don't know how many you can duplicate at one time, but I've duplicated 104 arrows at one time, so I'm pretty sure you're safe. ^_^
