The Witch's Staff
The distinction between wands and staffs often has to do with size: a staff is thicker and substitutes as a walking stick. In theory, a staff should be long and solid enough to lean on. Historically associated with ancient Egyptian and Semitic magick, staffs are associated with the Biblical Moses and his Egyptian opponents.
The modern staff is most associated with Obeah, the African-derived traditions native to the British West Indies. The Obeah Stick, also called an Obi Stick, is a carved wooden staff, usually featuring a serpent motif. The simpler ones are carved so that a snake-like groove encircles the staff. The more elaborate Staff of Moses usually features a snake carved from bottom to top. Staffs maybe hollowed out and filled with herbs.
