The Elder Scrolls V: Skyrim Special Edition Glitches

Infinite Gold
Travel southwest from Winterhold to a location called "Sightless Pit". Just above this location is an alter with a skeleton lying upon it and a copy of the Conjuration skill book "The Doors to Oblivion". Take the book, then kill all three skeletons that attack. Now go back to the corpse of the skeleton from the alter and loot it's entire contents. Back out of the loot screen then repeat the process. You will notice that each time you loot it's corpse, a copy of "The Doors to Oblivion" will re-spawn in it's inventory. Simply fill up your inventory with copies of this book, head to your chosen city and sell them all on, then fast travel to "Sightless Pit" and repeat.

And don't worry, the corpse doesn't de-spawn no matter how long you leave it, so free gold for life!
