You summon a virulent thunderstorm that lasts for the duration, damaging creatures in range with electric shocks. Once when you cast this spell and at the start of each of your turns, you may use a bonus action to call forth a 20-foot wide, 100-foot tall cylinder of storm and gale crashes down upon a point within the range of this spell. Creatures caught within the cylinder must make a Dexterity saving throw, with disadvantage if the target is not on the ground. A creature takes 1d12 lightning and 1d12 thunder damage on a failed save, or half as much damage on a successful one.
When the spell is cast as a ritual (A process which — unlike other rituals — requires 30 minutes of uninterrupted incantation and prayer) The spell also conjures forth a large storm cloud, 250 feet off the ground, with a radius the size of the spell's range centered on the caster, that randomly strikes flying targets with small bolts of lightning. At the start of each of your turns, you may make a ranged spell attack against a creature underneath the storm cloud, with disadvantage if the target is not within line of sight. On a hit, the target takes 3d6 lightning damage.
