Golden Key

Golden Keys are required to unlock the Locked Gold Chests found in the Dungeon, Old Shaking Chest in the Cavern Layer, and obtained by fishing in the Dungeon. A Golden Key is consumed upon use, so unlocking each Gold Chest will require an additional key.

Golden Keys can be acquired by:
 * Finding one in an unlocked normal Chest in the Dungeon.
 * Killing a Dungeon Slime (100% chance).
 * Killing any other Dungeon enemy (1/65 chance).
 * Breaking a Pot in the Dungeon (1/40 chance).
