Pot

Pots are common items generated at world creation in random areas. When broken with any weapon or tool, they have a chance to drop Coins and/or a random common item. The amount of items dropped is higher in Expert Mode. Furthermore, the amount of coins dropped increases with the number of different bosses defeated and the Wormhole Potions only drop in multiplayer. If you are lucky enough, breaking a Pot will cause a little golden mirror-like thing to appear, spawning 5, 10, or 15 Gold Coins. Pots cannot be picked up, never respawn, and cannot be crafted.
