Buy The Whiterun House Without Spending 5000 Coins
In order to buy the house in Whiterun, you'll need 5000 coins on hand, but you'll be able to keep it with this trick -- which makes use of your ability to turn your head around while talking to people. If you go to the man who sells you the house in Whiterun while he's asleep in his bed, he'll sit up to talk to you. Make sure you're standing in a place that you can open the nightstand or dresser next to the bed while you're talking to him. As soon as you agree to buy the house *immediately* open the dresser next to the bed and put your gold into it and return to the conversation. He'll give you the key, and then you can just get your gold back out of the dresser, as rich as you were before.

Create infinitely powerful weapons and armor
You would require the necessary perks in enchanting, alchemy, and smithing. First, enchant armor/boots/gloves (or whatever can be enchanted) with alchemy boosting properties. Now, equipping that gear, create a potion that enhances your enchanting skill for a certain amount of time. Now go back, drink the potion, and enchant new equipment with alchemy boosting properties again. Your new equipment with now boost your alchemy even more, which will allow you to create a potion that enhances your enchanting even more than the first potion you made. Rinse and repeat until you've whet your appetite of game-breaking goodness and finally create smith boosting equipment and a smith boosting potion. Go to the blacksmith and create your gear while you have your smith boosting equipment/potion and upgrade it to -truly- legendary stats. Ta-da.

Duplicate Any Apparel
Place any apparel item (armor or jewelry for better results) on any mannequin. Then place the item back into your inventory. Leave your location to another area (ie. Exit a house), then return to the area to find the item still on the mannequin. Successful duplication.

Early Sneak Skill and Level Up
Once you can get to Bleak Falls Barrow, go and talk to Sven to talk about his love troubles with this girl. Accept to deliver a fake letter to the girl he mentioned. Go find the girl and deliver the letter (lie) to her. After, go to Faendal and accept the Golden Claw quest. Go back to Sven and talk to him about the quest. Then tell him to follow you. Sneak behind and sneak attack Sven. You can do this as much as you want (as long as you don't kill him). For every sneak attacks, your sneak skill should increase, which increases your level progression. Sven gets mad at you obviously, but he never tries to attack you back. *NOTE*: DO NOT get the perk to increase one-handed weapons to do 6x damage. If you do, and you try to sneak attack after you get the perk, you'll do a sweet kill animation where you slit his throat. Sven dead = no more sneak attacks :( You could save up your perk points after each level up to get all the weapon sneak skill perks at once. (to avoid killing Sven) This method should also raise one-handed weapon skill (or whatever type of weapon you have equipped) as well.

Get free skill training
If you can get a skill trainer as your follower then you can get any training for free. Just train your skills and then ask them to trade and take the gold back.

Level Cheat
For all your power leveler's out there, I came across this online... When the beginning scene is finished you'll follow an Imperial to a small fort where you can continue to follow the Imperial or a Stormcloak (you can follow either for this to work). Whom ever you chose to follow will give you a small tutorial of the game as you escape the turmoil created in the beginning scene. As you go through the tutorial you will come to an underground cave where you'll be taught how to perform sneak attacks. At this point you'll be asked to either sneak attack a bear or sneak past it. Instead of doing either of these you can enter sneak mode and go behind which ever NPC is giving you the tutorial and attack him over and over again with no consequence since he will not retaliate or die. You can use this to level up your one-handed, sneak, two-handed, and destruction skills. I'ts better to get them into a corner because when you hit him he will be pushed forward. This is very useful if your willing to put the time into it.

Maximum speech glitch
Find Ungrien in Rifton and tell him "Tell Me about Maven Black-Briar." Choose the persuasion option. If you succeed, the option doesn't go away, and you can kep using it until you hit 100 in speech

Quick Gold Glitch
Go to Winterhold, start heading up the path as if you're going to do the dragon bounty for the jarl, you will come to a cave called the "Sightless Cavern". Continue past it up and around a corner, you will come to an alter with skeletons. Next to the alter there are Boots and a Shield. Picking them up will make the skeletons come alive. After killing them, the skeleton that was on the alter will have a "Book of Oblivion" in his inventory. This book will never disappear. Continue looting the body for an infinite number of books worth 50 gold each.

Steal More Easily
It's possible to steal items at any time of day, in any situation. All you need to do is pick up a basket, bucket, kettle, or any other "container" type item and place it over any NPC's head. With the item over their head, they will not be able to see you as you plunder their Soon-to-be-bankrupt shop. This trick does not, however, work for pickpocketing. It only works for stealing items off counters, shelves, etc. Lastly, there are a few, select NPC's that will not allow you to put the bucket, basket, etc. over their heads. It seems like they have a sort of 'bubble' around them that prevents it from fitting on their head for more than a few seconds.

Easy XP, Smithing, & Speech Skill
Every time you go to a forge, make sure to talk to the person in charge of it, and buy all the iron ingot and leather or leather strips they are selling. Then, make as many leather strips as it takes for each iron ingot. Take it to the forge, and make an iron dagger that only takes one of each ingredient to create. If you sell it back to the merchant, sell it one at a time so you create more transactions to level up the Speech skill

Oblivion bucket
Inside the museum of Dawnstar there is a yellowish piece of paper with the symbol for Oblivion on it inside one of the display cases. I you pick the lock and use a spell for a few seconds on the paper it will suddenly turn into a bucket. Nothing can be done with the bucket. Purely a thing of amusement.

Easy sneak skill increase
When you can reach the Greybeards at High Hrothgar you can level up your sneak skill in a very easy way. All you have to do is sneak behind one of the Greybeards and wait untill you become undetected. Then all you have to do is attack them and then repeat the Greybeards will not attack you in anyway and this is not a crime. You can use a weapon but you have the risk of killing them it works fine while unarmed.

Pick up Skill Books without reading them.
When you pick up a skill book that is not in a container, you will read it and gain a point in that skill. There is a way to avoid this; adding the book to your inventory so that you can save it for later use. This is useful for later in the game when it can be difficult to increase a skill. To use this method you need to have a companion, then; When you see a Skill Book in the game (cross-ref one of the FAQs for names; or look at the value of the book) talk to your companion and select the "I need you to do something" command. Then put the cursor on the book, and select it. The dialog box will tell the companion to "Read such-and-such book," but the companion will add it to their inventory. You can then take the book from then inventory to be read -- and the skill point gained, at your leisure.

Free house in Whiterun
Go into the castle and find Proventus Avenicci. For this glitch to work, you need to make sure he's by something you can store items in. (his bedroom has a wardrobe that's perfect for this glitch) Make sure you have 5000 gold and talk to him about buying the house. Select the answer "I'll take it" and immediately press "O" to back out of the conversation. Then quickly open up the wardrobe and store all your gold in it. You'll receive the key to the house, and then you can retrieve all your gold from the wardrobe.

Permanently dupe one item
A mannequin can duplicate any one piece of visible apparel (armor, clothes, rings, etc) indefinitely. To do this, go to the mannequin, store the visible armor, and exit out the menu. The mannequin should disappear, pardoning the hands. Go back into the mannequin, and equip any other piece of equipment that is a different type than the one you want to dupe. (if you want to dupe a chest piece, do no put another chest piece on it). Then exit out of the menu. The mannequin should still be invisible. Go back into the menu, and take back the piece you want to dupe. The mannequin should become visible with the second piece of armor on it. Leave the area, and re-enter. Your mannequin should be invisible again. When you check it again, it will still have a copy of the armor that you took off of it. Exit and re-enter whenever you want another copy. One thing to note, is that the mannequin will now always have that one thing on them, and I have yet to find a way to change what it dupes. So basically your one item will be "imprinted" onto the mannequin permanently. Voila!

Easy gold
When completing the quest to get married, marry a follower. Make them follow you and trade items. They should have 750 gold because of the store they run. Take the gold leave wait a day and rinse and repeat. As much gold as you need without having to sell anything!

Oghma Infinium Book (Infinite Skill Level Ups)
The bookeshelves maybe broken, but you can still use anything you can store the book in. You do NOT have to close the container either. 1. Open Chest (above bookshelf in whiterun for example) or any container you can store items in 2. Read the book in your inventory 3. Choose a path 4. Hit B then store the book 5 Scroll up to the "Chest" area and take the book (skips the (Do Not Read) part and the book does not open) 6. Repeat 1-6. This has been tested and confirmed by multiple people. Including myself and a friend of mine.

Keep the Rusty Mace and Mace of Molag Bal from House of Horrors
Equip the Rusty Mace. Click on any weapon mount in Hjerlim. This will remove the mace from your inventory even though it is a quest item. Finish the quest and receive the mace with unlocked potential, the Mace of Molag Bal. This can be used to keep other quest weapons that you are meant to give to others, since the game assumes it is impossible that the item is not in you inventory, quests continue as normal though you have kept the weapons for yourself.
