Gold is one of the features in Fate.
Gold can be found and aqcuired in the dungeon, after completing a quest, or after selling an item from the inventory. Gold is the way to buy things from townspeople or wanderes in the dungeon. Items usually cost more gold depending on how well it works, strength, etc. The easiest way to obtain gold is to simply complete quests for sometimes thousands of gold coins.
If you die in the dungeon, Fate gives you two options that force you to lose gold. One is that you are sent 1-2 dungeon levels higher or lower, but you must give a certain amount of gold, andthe other, much worse: You are transported 3 levels up but all of your gold stays for a time, meaning that if you are not fast enough, all of the gold left on the level is erased for good.
