The wind picks up over a lonely town. The sky darkens and there is no sun to be seen or felt under the massive black cloud that you have conjured.
You extend both hands, uttering ancient words of the Gods. A 2km by 2km cloud appears over a place of your choice. Black tinged lightning dances around you. Anyone under the cloud must make a Dexterity saving throw. Anyone who fails is hit by a dark bolt of lightning and takes 25d8 lightning damage and 25d8 necrotic damage or half as much on a successful save. The lightning strikes anyone outside, under the cloud every turn except you. You may call down lightning onto any target you choose as your action until the spell ends.
If the spell is dispelled or ends some other way before the hour is up, you get the expended spell slot you used for this spell.
