This rope exactly resembles a rope of climbing or entanglement, but as soon as it is commanded to perform some action, it lashes itself about the neck of the character holding it, and from 1-4 others within 10-ft of the victim (each entitled to a saving throw versus magic) and strangles and crushes the life from each and every such victim. 

Each round it delivers 2-12 hit points of damage, and it will continue to constrict until a dispel magic is cast upon it. 

Note that any creature entwined by the rope cannot cast spells or otherwise free himself or herself by any means. 

This rope is AC -2 and takes 22 hit points to cut through; all hit points must be inflicted by the same creature (not the one entangled).

Note: Any magical rope which is broken or severed will immediately lose its special properties.
