1 minute/mana

As two actions, a 10-meter radius storm cloud appears centered on a point you can see within 20 meters directly above you. The spell fails if you can’t see a point in the air where the storm cloud could appear (for example, if you are in a room that can’t accommodate the cloud). The cloud moves to always stay directly above you.

When you cast the spell—and once on on each of your turns thereafter as an action—you can choose a point you can see within 10 meters. A bolt of lightning flashes down from the cloud to that point. Each creature within 1 meter of that point must make a Reflex saving throw.

On a failure, it takes 2d12 lightning damage and is deafened and can’t take reactions until the end of its next turn.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

If you are outdoors in stormy conditions when you cast this spell, the spell gives you control over the existing storm instead of creating a new one. Under such conditions, each creature within 2 meters of the point must make the saving throw.

Augment

You can increase the damage by 1d12 for each additional mana expended.
