The crystal chest is a treasure chest located in the Edgeville bank. The chest is locked and can only be opened by a crystal key. Attempting to open the chest without the crystal key yields the message: "This chest is locked." The crystal key is made up of a loop half of a key and a tooth half of a key; you can make the crystal key by using them with each other.
Opening a crystal chest grants a variety of rewards.
