The subject must succeed on a Reflex save or be immobilized.

The subject remains immobilized for as long as you concentrate. Should you cease concentrating, the subject may attempt to end the spell as a full-round action, either by breaking the bands (Strength DC 15) or slipping free (Escape Artist DC 15).
