"A fancy staff infused with both solar and lunar power."
The Sun and Moon Staff is one of the most powerful weapons in Vulpin Adventure. When a Vulpin equips it, they gain an attack boost of 20. As its name describes, it is a staff with both sun and moon imagery decorating it, with a large carving depicting the sun at the front end and a smaller carving depicting a crescent moon at the back.
You can bet the Sun and Moon Staff by investigating the Lanterns. Due to its powerful nature, however, it is often considered worth doing some exploring to find the Staff before moving on to more powerful enemies.
