"Hero Saves"
Perform any quest up to the point that you earn a large sum of money. Use a "hero save" and immediately reload the game. Your quest will reset from the beginning, but you will retain everything you earned prior to saving. The "Arena" is an excellent quest to earn the same reward several times using this tactic.
Tavern Games
Several of the tavern games require hand-eye coordination to win and earn money. Purchase the "slow time" spell and cast it during tavern games to win more easily and avoid accumulating evil character points.
Home Rentals
Purchase a home and furnish it with expensive furniture and trophies. Break the doors using your weapon and rent the home out. Sell the home for an inflated price, then re-enter through the open-door way. Retrieve your trophies and exit the home. Purchase the home again at the original price and repeat the process as needed while avoiding evil points.
Stealing Glitches
Evil characters can steal goods from merchants and resell the same items back for 100 percent profit. Ask the merchant to follow you outside and give them a few beers to allow more time to loot their inventory. Concentrate on vendors with high ticket items such as gems and jewelry to maximize profit.
