You weave golden threads of holy light, forming a radiant cage around a creature you can see within 30 feet. The target must be Huge or smaller. The shimmering threads hang in the air like a divine spiderweb, restricting the creature’s movement.   If the creature attempts to move at least 5 feet outside the cage, the threads snap and lash toward it in a blinding surge of radiant power. The target must make a Dexterity saving throw, taking 8d8 radiant damage on a failed save, or half as much on a success. The threads then dissolve, and the spell ends.
