Duplicate itemsIn order to duplicate items, you'll need to equip a bow and arrow. While the bow is drawn back, go to the inventory screen by pressing B. Choose the arrows which you are using and then select the item to be duplicated. Drop the item by pushing the X button, and then go out from the equipment screen. Resume the gameplay. The dropped item will be duplicated. So, if you have 15 arrows, you can make 15 copies and sell the duplicated items for a good income boost. This is a great way to get healing potions. You can also duplicate Soul Gems, to recharge items on the fly and for free. However, this trick doesn't work with all weapons or objects and the game is known to freeze, should you hold more than 250 copies of the same item.
Free movable storageThe horse Shadowmere is a hero character and one of the advantages is that you can't kill him. But - at the same time - he is an animal, so you can loot his corpse when he is knocked unconscious. The thing is you can stock up items in his inventory, and conveniently remove them at any given time by repeating the process. Items stored this way don't disappear, so use your newly found pack mule with confidence. You can get Shadowmere at Fort Farrgut. Knock him unconscious and, when he is lying on the ground, you can loot his body like any normal corpse. Place any items you wish to transport into his corpse's inventory. Let him get up and then go and take him wherever you want. To get the items back, you can knock him out and take them out. You can have items in him for as long as you want. In fact, he will still have your items even if he spawns back at the Fort Farrgut.
See through wallsThere
is a way to get visibility beyond normal boundaries, straight through almost any wall. You will just need some magic staff of any kind. Deplete the staff's uses to 0, then face the wall and walk up to it and attack it. While attacking, you'll be able to see what lies on the other side. It's of particularly great help in caves.
Lockpick glitchUsing this glitch you'll be able to open up most locks in the game, even the most difficult ones. You need to deal with the first spring manually. As you press over on the joystick to go to the next spring, hit the "X" button a split second after you press over. The arrow should be in between the 1st and 2nd springs as you hit "X." Do this correctly, and you'll get locks open on the very first try.
