Selûne's Spear of Night is a legendary Spear that allows the wielder to cast Moonbeam and grants Advantage on Wisdom Saving Throws and Perception Checks.
'One of the goddess Selûne's titles, Moonmaiden, has often been debated among the ecclesiastical. Common symbology certainly rejects the assumption of virginity. More to the point, 'maiden' itself carries some dusty connotations. How about Lunar Lady? Keeps the alliteration, too' - Margaery Henderplum
