This is probably the most straightforward of the glitches I found. It's a very simple way to have infinite gold, and it works pretty much like if your were printing money. This glitch let you generate 20 gold per second, and you just have to let it run.
All you need are:
21 gold pieces
A Sussur Bloom. They can be found in the Underdark and you're not supposed to be able to bring them to the surface, but I stuck mine in a chest, sent the chest to camp, and once in camp I could open the chest and get back my flower.
And the Chest of the Mundane that you find in the Underdark as well.
Keep the Sussur Bloom on yourself. You should emanate an anti-magic field.
Drop the Chest in front of you.
Open it and drop 21 gold in it.
Now, walk away. As the chest is no longer in the area of anti-magic, it will start printing money, 20 gold/second. It makes an horrible noise.
When you think you have enough, come back to the Chest. When you'll be close enough for the anti-magic field to activate, it will trigger an effect that looks like a giant black orb of doom.
Open the chest and loot.
Enjoy!
It's not like Gold is of any use in the game once you have a good enough pickpocket score anyway.
You don't actually need to have the Chest on the ground for the glitch to work, you can make it work from your inventory, but it was just more dramatic that way. If you operate it from the inventory, you need to drop the chest (so the anti-magic zone triggers) for it to stop printing money.
UPDATE:
Well, it seem that it doesn't work all the time. The Chest need to be primed first, and put into a glitchy state where some items are displayed in slots where they shouldn't be. I did drop all my pouches/burlap sacks/backpacks into it, as well as two sussur flowers, then looted all.
Some items couldn't be looted and stayed in the chest, and it was enough to prime it for the glitch. Maybe it's because of the Bags Bags Bags mod I have been using, maybe not.
