Easy gold:
Go to the Mages Guild in Chorrol. Once inside, join the guild if you have not already. Now, look around. There is a display case table either hard or very hard on the first floor that has what looks like a glowing white dot inside. Break into that display case. Because you are already in the Mages Guild you can take whatever you want. Take the glowing white dot. It is a flawless diamond worth 100 gold with a weight of 0.1. Use the "Duplicate item" glitch on it until you have as many as you wish to sell. If you have any strength at all, you will be able to carry around 50,000 gold worth at least. Go to any jewelry or weapons shop and sell them. You can have around 100,000 gold in about ten minutes. Note: Make sure not to sell your last diamond, as you may not be able to buy it back to get more money.

Easy lockpick use:
While unlocking a door, press Up on a key, then immediately pause game play afterwards. , Look at the tab you raised up. If it is mostly up and about to reach the top, resume the game and do it again. If it is mostly half-way or mostly down, resume the game and immediately press A. You should have that tab done. Continue on with the next tab. This might require a few attempts, but after you have done it once it should be easy.

You can open locks more effectively if you listen closely to the sounds of the clicks the tumblers make when you hit them. Try hitting them when they click twice.

To break into a house or chest easier, pay attention to the speed of the tumblers when they drop. If you try after the tumbler fell fast, you will have a much better chance of keeping the tumbler up.

Unlimited arrows:
For an unlimited source of iron arrows, go to the Bloodworks in the arena. One of the gladiators is practicing with his bow on a target. Stand close by. When there are five to ten arrows in the target, take them before he does. He will just continue shooting when you move out of the way. This is an unlimited source of iron arrows, which can be sold to almost any merchant and therefore also makes an unlimited source of gold.

When you are at the Inn of Ill Omen, go outside where the man is practicing his archery.He is using steel arrows. Go in front of him and pick up the arrows. He will not hit you. He will wait until you move out of his way. You will not get into trouble with the guards. You can do this as many times as desired.

Go to Cheydinhal and break into Bazur gro-Gharz's house. When you kill him, search his body. He will have unlimited steel arrows.
