The Gold Chest is a naturally-occurring item used for storage. It is identical to the standard Chest except in appearance, but it typically has a larger sum of coins inside when found initially. A pickaxe can be used to remove an empty Gold Chest that is placed, which in turn can then be picked up. It has 40 slots for storage of items, and can not be crafted or purchased.
Gold Chests in the dungeon will be locked, and require the character to have a Golden Key in order to open them. When the key is used, the Locked Gold Chest will instantly become a normal Gold Chest.
Gold Chests can only be found in Worlds created after 1.0.5 update.
