A series of luminous chains spring up from the ground and wrap around a creature within range, provided the creature isn't flying or hovering. The target must make a Strength saving throw. On a failed save, the target takes 1d6 radiant damage and becomes immobilized. Moreover, the creature can't move or be moved more than 10 feet in any direction.

The spell's damage increases by 1d6 as a 5th (2d6), 11th (3d6), and 17th-level (4d6) spellcaster.
