One end of this pile of pungent-smelling intestines has been tied with an intricate knot.

Once per day, you can command this 50-foot rope to grow up to 350 feet in length. Any length beyond the original 50 feet decays to nothingness after 12 hours. If the large knot on one end is ever untied or cut open, the rope’s magic is destroyed.

Prerequisites: Craft Wondrous Item, minor creation.
