While holding this 10—foot pole, you can use an action to speak a command word and cause it to collapse into a l-foot-long rod, for ease of storage. The poles weight doesn't change. You can use an action to speak a different command word and cause the rod to revert to a pole; however, the rod will elongate only as far as the surrounding space allows.
