 * Possible reward from opening a Mystery box in all random events.
 * Found during Treasure Trails when the clue requires you to dig somewhere or perform emotes.
 * Warning: If you get a Casket in the Wilderness, it is recommended not to open it there. Wait until you are out of the Wilderness to open it.
