Uan, the currency in Harbinger, is so common to the point that it is worthless. At first, like most games, you start with nothing but the basic equipment and no money. Later on, as you break through the quests and enemies, you begin to accumulate wealth from picking up Uan dropped by enemies or selling equipment. You will begin to see the problem with the "economy" when you find numerous weapons you find useless or usable due to your class. It becomes worse when you factor in the tendency of the store to rarely update its content based on your power-growth, meaning that you will keep on selling items without buying anything back. What made a game like Diablo famous were the numerous items that you could spend your gold on and the stores that constantly updated their inventories. You could fight for ten minutes in a dungeon, go back, and see the entire inventory changed, ready to steal your gold. This isn?t the case here, where you have nothing to look forward to except for cleaning up your inventory full of junk. The majority of the items you will get are from fallen tough enemies, not from the store.​
