Divine Cataclysm

You call down the full might of your deity upon your foes. Choose a point you can see within range. Every creature of your choice in a 60-foot radius centered on that point must make a Constitution saving throw. On a failed save, creatures take 28d6 radiant damage, or half as much on a successful save.

In addition, any undead or fiends in the area take an extra 10d6 radiant damage and must make a Wisdom saving throw or be stunned until the end of their next turn.

If a creature is reduced to 0 HP by this spell, it is disintegrated instead of leaving a corpse.
