Well first of all get your conjuring skill to 50 so you can make your daedric armour spell last longer, once you have all the spells and they are more than 10 secs summon a monster and attack it until it attacks you, it should damage the daedric piece you got on, then repair it with a repair hammer, then drop the deadric armour you just repaired. Once you done that do not pick it up until the spell timer has run out. Once it has you got a nice piece of deadric for free. XD
