Infinite Money - Dorian

This glitch specifically occurs with the NPC Dorian, who lives in the Talos Plaza District in the Imperial City. If you kill him, you can repeatedly loot his corpse for gold, and the gold never disappears from
his body. You can keep doing this until eventually after a few days his body disappears. (If you clear the hard drive cache on the XBox, by holding A as the game boots, his body will no longer be there). When collecting the gold, do not select "Take All" or the game may freeze.

The amount of gold that he initially has is random. To increase the amount of gold on his corpse, you can spend time bribing him before killing him. Repeatedly bribe him until his disposition has reached its maximum. To add even more gold, attack him then yield, and start over again.

If you are a stealth-oriented character or are just quick with a blade, weapon or spell, you can quickly kill Dorian without the alerting guards. If you are not able to kill him quickly, it is best to first corner him so he can not run away. A good place to do this is the upstairs room in his house. First unlock and open the upstairs doors, then go back downstairs, find Dorian, and hit him once. With him chasing you, run upstairs to his room, close the door, and stand in front of it so he can not run away. Kill him and loot his corpse for the gold. By this time, the guards will have been alerted, so be sure to drop any stolen goods you are carrying before the Imperial Officer shows up. Choose to pay your bounty, using the gold you just looted from Dorian. Once you've finished settling the tab, return to Dorian's house, retrieve your stolen goods, and start looting Dorian's gold.

The post-patch version of this glitch has two different methods. The first method is to paralyze Dorian and loot his body while he is paralyzed. This requires you to be a journeyman in illusion. If you do not meet this requirement, then you can try the second method, which is to damage his fatigue until he falls down. You can then loot his body.

Infinite Money - Kvatch

This exploit allows you to sell a weapon repeatedly to a merchant, receiving gold each time but without giving up the weapon. To do it you must first equip any weapon (you actually have to have it equipped so you can see it) and then mount a horse. Go to Kvatch and talk to Batul gra-Sharob, the female Orc merchant found outside there, without dismounting from your horse. (The other Kvatch merchant, Sigrid, will only work for this if your mercantile skill is 50.) Sell the merchant the weapon that you previously equipped. A message saying "this item cannot be unequipped" will come up but you will still get the gold for it. Rinse and repeat! The merchants have 200 gold each but if you are a master mercantile you can get 700. This only works with weapons, and you must be on a horse.

Infinite Money - Vampirism

At the end of the Vampire Cure quest, Janus Hassildor gives you a cash reward. However, the Reward topic does not disappear, and you can repeatedly talk to him about a reward; he will give you more gold each time. This glitch occurs whether you have already used your own vampire cure potion or not. The amount of the cash reward is level-dependent, see Reward; the reward amount can change if you level up after completing the quest.
