Confiteor

You summon three miniature blades of Truth, Faith, and Valor, which float in the air near you for the spell’s duration. When you cast the spell — and as an action on each of your turns thereafter — you can expend one of the blades, calling ethereal swords to strike down upon a point you choose within 120 feet of you. Each creature within 15 feet of the point you chose must make a Dexterity saving throw. A creature takes 8d6 slashing damage on a failed save, or half as much damage on a successful one. Additionally, on a failed save, an affected creature becomes vulnerable to radiant damage for 10 minutes, if they were not already. (All radiant damage done to that target is doubled)
