Bonds of Icharus

Ropes grow over the creature you touch and bind them to the ground. It takes a DC 40 strength check to get out of the ropes (DC 30 if you are cutting them).  In addition, the ropes deal 1 point of damage to the creature every minute. If its hit points become halved, it must make a constitution save or die instantly. Every time it takes damage after this it must make the save again, until it dies or the spell ends. If the spell ends before it dies, it still cannot regain lost hit points for 1 day. The ropes remain until the spell ends by being dispelled by an arcane spellcaster of 11th level or higher.
