Anger of the Gods

You call upon divine wrath, unleashing a wave of world-shattering flame that scours the battlefield. The sky splits open and begins to weep tears of divine fire accompanied by harsh, searing winds. Each creature other than you that starts its turn in the area or enters it for the first time on a turn must make a Dexterity saving throw, taking 6d10 fire damage on a failure, or half as much on a success. A creature reduced to 0 hit points by this damage is utterly destroyed—its body is reduced to ash and blown away on the winds. The fiery rain ignites flammable objects in the area that aren't being worn or carried. Creatures without a clear view to the sky are unaffected by this spell unless they are only protected by thin, flammable protection like a cloak.   At Higher Levels. When you cast this spell using a higher level spell slot, increase the damage by 1d10 for each slot level above its base level.
