Staff

staff, n. 1. a long stick, usu. of wood, carried in the hand for support while walking; pl. staves; from Middle English staf, Old English stæf. 2. in fantasy milieux, a magical artifact, similar to a wand, carried by a mage. [GJ1]

Addendum: The idea of a staff as a magical object was popularized by Gandalf's staff in LOTR. In Tolkien, Gandalf's staff was not actually magical, and merely served as a prop or focus for his power. BTW, newbies, there is no such word as "staffs." [GJ1]
