object or to unfasten itself, to knot or unknot itself, or to coil itself for carrying.
If you tell the rope to knot, large knots appear in 1-foot intervals along the rope. While
knotted, the rope shortens to a 50-foot length and grants advantage on checks made to climb it.
The rope has AC20 and 20 hit points. It regains 1 hit point every 5 minutes as long
as it has at least 1 hit point. If the rope drops to 0 hit points, it is destroyed.
