This spell creates an enormous black storm cloud. Lightning and crashing claps of thunder appear within the storm.

Each creature beneath the cloud is subjected to the following effects:

  1. Must succeed on a Fortitude save or be deafened for 1d4 × 10 minutes.

  2. Acid rains down in the area, dealing 1d6 points of acid damage (no save).

  3. You call six bolts of lightning down from the cloud. You decide where the bolts strike. No two bolts may be directed at the same target. Each bolt deals 10d6 points of electricity damage. A creature struck can attempt a Reflex save for half damage.

  4. Hailstones rain down in the area, dealing 5d6 points of bludgeoning damage (no save).

  5. Violent rain and wind gusts reduce visibility. The rain obscures all sight, including darkvision, beyond 5 feet. A creature 5 feet away has concealment (attacks have a 20% miss chance). Creatures farther away have total concealment (50% miss chance, and the attacker cannot use sight to locate the target). Speed is reduced by three-quarters.

Ranged attacks within the area of the storm are impossible. Spells cast within the area are disrupted unless the caster succeeds on a Concentration check against a DC equal to the storm of vengeance’s save DC + the level of the spell the caster is trying to cast.

Augment: For every additional spell point you spend, the damage dealt by each aspect of the storm (the acid, each lightning bolt, and the hailstones) increases by one die (d6).
