There's a quick, easy glitch that allows you to dupe gold or anything else. You just need a 2nd controller with a 2nd character logged into your game. Then use player 1 to "gift" player 2 whatever you want to dupe, then leave player 1's sanctuary. Have player 2 go into his sanctuary and find the gift. Now have him reject the gift to send it back to player 1. Immediately have player 2 leave his sanctuary then immediately drop him from the game. Now player 1 has a rejected gift in his sanctuary and player 2 will not be saved, meaning when you reload him, he will also have a gift the game didn't save as being rejected. Dupe! You can dupe up to 100k gold at a time using this.
