Description: You place a glowing seal on a creature or object within range. At the start of your next turn, the seal explodes in radiant light. Creatures within 10 feet of the seal must make a Dexterity saving throw (DC = 8 + your proficiency bonus + your Wisdom modifier), taking 6d8 radiant damage on a failed save or half as much on a success. A creature targeted by the seal automatically fails the save.
