for this you need a conjuration level over 50, a level 14 or over character wich has high endurance and the spell wich summons the peace of deadric armor you want,"bound", wich can be bought from the chorrol mages guild and 40gold for every piece of armor you want. after buying the piece of bound armor that you want go and attack any guard in the whole of cyrodiil but do this in the night so that nobody will interfere and when the guard starts attacking you summon the armor and let the guard hit you 4 times. now quickly yield to him by holding up your shield and talking to him and then when he talks to you again select "pay gold" and you will be taken to the castle. now quickly press B to go onto the menu and use a repair hammer on the selected piece of bound armor, after this dont go off the menu but unequip the bound armor and and drop it. then go off the menu and wait until the spell for the armor runs out and simply pick up the bound armor you dropped and DA NA!!! a piece of deadric armor. i have done this and now have the full deadric armor set! this also works for deadric weapons but ive drunk to much skooma and my intelligence is to low to summon weapons.
