Grinning Skull

Wondrous item, fabled (5th-level and higher properties require attunement by a cleric, sorcerer, warlock, or wizard)

While holding this skull, you can use an action to speak a command word, causing light to shine from the sigils and symbols etched into the skull. The skull sheds bright light in a 20-foot radius and dim light for an additional 20 feet. The light lasts until you use a bonus action to speak the command word again. In addition, you can use an action to shrink the skull to the size of a marble for easy transport. None of the skull’s properties function when it is this size, however. You can use a bonus action to return the skull to its normal size.
