Pot

Pots are common items generated at world creation in random areas. When broken with any weapon or tool, they will either drop Coins and/or a random common item, or spawn a Coin Portal. 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. Pots cannot be picked up, never respawn, and cannot be crafted.

As of 1.3, there is a rare chance for a coin portal to appear upon smashing a pot, which will yield 15 gold coins. This is true for both Normal and Expert mode.
