Divine Blast

A blazing streak flashes from your palm to a point you choose within range and then roars into an explosion of brilliant radiant energy. Each creature in a 20-foot-radius sphere centered on that point must make a Constitution saving throw. A target takes 10d6 radiant damage and is blinded for one minute on a failed save, or half as much damage on a successful one without being blinded. An effected creature may reroll the constitution save at the end of their turn to remove the blinded state.
