Convergent Wrath

You cause numerous lightning bolts to simultaneously converge in an electrical explosion.

Each creature in a 5 ft. Emanation originating from a point you can see within range makes a Dexterity saving throw, taking 8d6 Lightning damage on a failure, or half as much damage on a success.

The effect then repeats twice more (including making additional Dexterity saving throws), increasing in severity each time and totaling 3 bolts of lightning. Each subsequent bolt deals an additional 4d6 Lightning damage, and the Emanation's size increases by 10 ft. than the previous one.

If you are outside under stormy weather when you cast this spell, creatures have Disadvantage on their saving throws against this spell.
