Wrath of the Gods

You channel the wrath of the gods through yourself in the form of a divine blast of energy. Each creature within a 10-foot-radius sphere centered on yourself must make a Strength saving throw. A creature takes 3d6 force damage, 3d6 radiant damage, is pushed back 5 feet from you and knocked prone on a failed save, or half as much damage and is pushed back 5 feet from you on a successful one. You are not required to make the saving throw, nor do you suffer damage from the spell.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the radiant damage increases by 1d6 for each slot level above 3rd.
