Catstaff

A catstaff was a magical weapon and item that granted thief-like abilities.

Description
The typical catstaff was a 7-foot-long (2.1 meters) quarterstaff made of stout, black wood. It contained secret compartments for carrying small items (e.g., thieves' tools and material spell components) and was topped with a sculpted cat-head knob. Using it as a weapon did not disrupt or prevent any of its magical effects.

Powers
The bearer of a catstaff was imbued with a thief's skill at stealth and climbing walls (provided both hands were free), along with 60-foot (18-meter) infravision. They could also cast shadow six times per day, creating a 10-foot-radius (3 meters) globe of semidarkness for 10 to 50 minutes that blocked the bearer from vision and, thus, gazes and other visual attacks. A catstaff lost all of its magical powers if it was broken in two.
