This cheat requires access to the Arcane University, a Chameleon spell, two rings, a necklace / amulet, two pieces of armor (preferably a helmet and a shield – you can use any armor for this, but you may want to enchant them with defensive magic. ). later), five Grand Soul Gems with Grand Souls in them and 8,000 gold. Go to Chironasio (enchantment section) in Arcane University. Go to a charming stall and enchant the necklace, rings, and armor with a Chameleon spell using the Grand Soul Gems. Each enchantment gives you a 20% Chameleon effect, so all five enchantments will turn you into a 100% Chameleon, which is not only invisible but also allows you to attack, steal, open and collect without being revealed. Now you can rob a store without the merchants doing anything. Your enemies will also stay put without being able to attack, allowing you to enter Sneak mode and attack for 4 to 6 times the damage, and steal without consequences (except for guards who can catch you if you miss, but still cannot attack you if you resist arrest). -From: andre.morgan
Equip a bow and any set of arrows, then pull your bow back. While checking out, press B to go to the inventory screen. Select the arrows you are using, then go to the item you want to duplicate. Press X to drop the item, then exit the computer screen and resume the game. The item you dropped will be duplicated. You can collect all the duplicates and use or sell them. The number of copies of an item you make depends on how many arrows you have equipped. For example, 10 arrows allow 10 copies. This works with most items and weapons, but not all. Note: Do not try to duplicate more than 250 copies of an item or the game may freeze.
Use the following trick for duplication or a permanent enchantment. You can duplicate an item that can be dropped, and if that item can be equipped with constant-effect enchantments, you can make them permanent. However, the item once made permanent cannot be re-equipped, but each enchanted item is different. You can use the “Duplicate Items” trick to make as many as you want and then sell them. Use the “Duplicate Elements” trick with a bow and arrows to duplicate the elements and make them permanent. Equip one of the items you want to make permanent. There must be an unequipped version still in your inventory for this to work. Use the “Duplicate elements” trick again; however, you drop the unequipped version of the item you have equipped and want to make it permanent. The equipped and the others will drop and you will never be able to equip that item again, but if you check your stats, the bonuses on the items will be permanent. You can duplicate anything that can be dropped, including Grand Soul Gems with captured Grand Souls.
This trick only works with portable items. Take any item that can be worn with a magical enchantment that you wish to make permanent and use the “Duplicate Items” cheat to double it twice so that you have two of that item. Pick up the item and equip one. While you’re using that item, double the one you’re not using by at least four. Note: The number of arrows used determines how many copies are made. Both items will fall to the ground in stacks of two. You will no longer use that item, but it will still have its effects. Note: these effects are permanent. Do not try this with any item with an effect that you want to remove later, such as Water Walking, Night Eye, etc.
Use the “Duplicate Items” cheat on a potion of good health. Repeat the doubling to get the desired amount of potions. Open the inventory screen and go to the strong potion of health. Hold down Y and quickly connect it to one of the directions on the analog stick. When you’re low on health, just tap the hotkey direction to use a potion. When you run out of health potions, repeat the doubling process.
Use the “Duplicate Items” cheat on a soul gem. Collect them all. When an item is low on charge, you can fully recharge it without spending money on Soul Gems or having to worry about catching souls.
Go to the Talos Plaza district of Imperial City and find a house owned by a man named Dorian (Dorian’s house) in the southeastern section of the district. Break into his house and find him. When he tells you to go, kill him. Don’t press X to loot it and take everything. Instead, take each item individually, ending with the gold, which won’t run out once you hit 8 pieces. Just keep selecting the gold he’s wearing and keep pressing A as usual. Do this repeatedly, and the number of remaining gold pieces will freeze when it is reduced to 8 gold pieces. It won’t go any lower, but will continue to give you as much gold as you want. Note: After you go in and he tells you to get out, talk to him. Go to “Persuade” and get a lot of it. After that, kill him. You now have more money to loot, making it easier to get there faster.
