You need to loot a skeleton that has book worth 50 gold. The book continually re-spawns. Best to get a companion with you so you can carry more. See the video below. Thanks goes to motherofgod4 for the video.
Unlimited XP Glitch
You need to obtain a book called Oghma Infinium that will give you unlimited skill points by continually opening it. The trick is to make sure you read it from the bookshelf menu then not read it. Sound confusing? There's a step guide and video below. Many thanks to Jeff from Respawn Videos for the video.
1. Complete the Hermaeus Mora Daedric (link) quest to obtain the Oghma Infinium book (DO NOT READ THE BOOK)
2. Take the book and activate a bookshelf - the video guide recommends using the bookshelf in your house.
3. Instead of STORING the book , read it from the menu.
4. Choose any of the three paths
5. Then back out to the inventory and store the book.
6. Next, target the book and confirm "Read Oghma Infinium" but then select DO NOT READ, and REMOVE the book off the shelf.
7. Repeat from Step 2.
How To 100,000K Damage Weapons Glitch
The glitch invloves creating a Fortify Restoration poition, drinking it which increases your worn enchanted Fortfy Alchemy apparel percentage sky high. You don't even need to have a high level of Alchemy. There's a video below which shows you exactly what to do. BE WARNED, this glitch has apparently been patched , so you will need to read this on how to remove updates.
The first thing you will need are the ingredients to make the potions. To save time, here's where to find them. If you have a low alchemy skill, make sure you get enough to make a lot more potions.
Fortify Restoration Potion
Abecean Longfin
Cyrodil Spdetail
Salt Pile
Small Antlers
Small Pearl
You only need any two of the above and the fish and salt pile can be found in Riften docks in fish barrels or some merchants.
Foritify Smithing Potion
Blisterwort
Glowing Mushrooms
Sabre Cat Tooth
Spriggan Sap
Again you only need any two of the above. Can be bought at merchants, but I found about 15 Glowing Mushrooms on the exit at Bleak Falls Barrow.
Fortify Enchanting
Blue Butterfly Wings
Hargraven Claw
Snowberries
Again you only need any two of the above. Can be bought at merchants. I found Blue Butterflies around Solitude and Snowberries around Dawnstar.
Once you have the ingredients, you will need armour or any apparel that fortifies Alchemy. You don't need to wear four pieces as in the video, but it helps and the percentage does not need to be high. If it is low, it will take longer and a lot more potions. For research purposes (cough) I tried this glitch myself and managed to get a sword to 2790 damage rating in a couple of minutes. I had worn four pieces of 15% fortify Alchemy and the Fortify Smithing potion created was 11510 % strong. Interestingly, the weapon created was worth over a million gold.
