Infinite Gold
You can earn infinite gold by taking advantage of a game glitch that is possible thanks to the free items your party members give you as you are about to begin a quest. Just follow the process below. Place 2-4 characters in your party who award you the same provision menu item. This is most easily accomplished by creating multiples of a particular class in the Stage Coach. Access the Provision menu. Just select any random quest, which you won't actually have to initiate and complete. Sell any of the items your characters provided you once the quest was selected. You can sell any duplicate items, until only one unit of the item in question remains in your inventory. For example, you might have three Medicinal Herb items if your party includes two Jesters and a Leper, since those characters all produce that particular item. You can sell two of them. Return to the quest menu without initiating the quest. You get to keep the money you gained from the sale of the duplicate items. Repeat as often as desired.
