You force one humanoid you see to make a Dexterity saving throw. On a failed save, magical ropes wrap tightly around them and their speed is reduced to 5 feet. If they try to make during this time they must make the save again, taking 4d6 force damage on a failed save or half as much on a successful one. In addition, a creature that fails the save is unwrapped, but is paralyzed until the spell ends. They may repeat the save at the end of each of their turns, ending the effect on a success.
