This small brown bag appears perfectly normal. However, when the command word is altered the posessor can pull from it a small black disc and throw it, at which point it becomes a portable hole or can cause a tunnel 10 ft. in diameter and up to 90 ft. in length to form in any non-magical structure. Only five holes can be created through this method per day. Only five portable holes created by this method can exist at any one time.
