On failure, it takes 3d6 fire damage and its movement speed is reduced to zero for the duration of the spell. On success, they take half as much damage and are not bound. At the end of each of their turns, the target repeats its saving throw. On a success, the chains broken and the spell ends for that target. On a failure, it remains bound and takes an additional 2d6 fire damage as it is seared by the chains.
