You bind a creature to a location, cursing it so that it may never leave. Choose a target and a location within range, both of which you must be able to see. The target must make a Charisma saving throw (a willing creature may choose to fail this save), or be permanently bound to the chosen location. The target may act and move around freely, as long as it remains within 20 feet of the point it is bound to. If the target begins its turn outside of this area, it takes 15d6 force damage and must make a Strength saving throw against your spell save DC or be dragged back towards the point it was bound to.   In addition, if the creature attempts to teleport or use any other means of extraplanar travel, it must make another Charisma saving throw. On a failure the travel attempt fails, and any resources used are wasted. On a success, the curse is suppressed until the creature returns to the plane on which it was bound, at which point the dragging effect resumes.   This spell can be broken only by the dispel magic spell or similar effects.
