All 15 Daedric Artifacts
When you progress to a certain quest in the main storyline called 'Blood of the Daedra', Martin requires you to give him a daedric artifact and warns you that this will remove the artifact from the face of Tamriel. Now if you are a collector and want to have one of every item in the game, then there is a simple way to get around this. There are 4 Daedric items which can actually be cloned unlike the others, these items are the Ring of Namira, Azura's Star, Wabbajack and the Ring of Kahjiiti. Using a duplication glitch clone one of the above mentioned items and you will be able to have all daedric artifacts still in your posession after this quest.
