Devine Wrath

You open a gateway to the heavens, unleashing a barrage of radiant engery at tremendous velocity toward your enimies. You pick four different points you can see within range. Each creature in a 40-foot-radius sphere centered on each point you choose must make a Dexterity saving throw. On a failed save, a creature takes 20d8 radiant damage and 20d8 force damage and is stunned until your next turn. On a successful save, it takes half as much damage and isn't stunned by this spell. A creature in the area of more than one radiant burst is affected only once.
