Storm of Vengeance (Invocation/Evocation)
Level: Cleric 8, Druid 8
Range: visual range of the caster
Casting Time: 1 round
Duration: 10 rounds
Area of Effect: 60 foot radius storm cloud
Saving Throw: none

This spell creates an enormous black storm cloud. Lightning and crashing claps of thunder appear within the storm. Creatures beneath the cloud must succeed a saving throw or be deafened (see blindness/deafness) for 4D4 rounds.

Each effect occurs after the first round.

Second Round: Acid rains down in the area, dealing 10d6 points of acid damage. Affected targets suffer 1d6 points of acid damage per round for 10 rounds thereafter. A saving throw halves all the damage.

Third Round: Bolts of lightning are evoked down from the cloud to strike any creatures inside the cloud, harming only enemies however. Each bolt deals 10d6 points of electricity damage. Creatures struck can attempt a saving throw against spells for half damage.

Fourth Round: Hailstones rain down in the area, dealing 10d6 points of damage. A saving throw reduces the damage by one-half.

Fifth through Tenth Rounds: Violent rain and wind gusts reduce visibility. The rain obscures all sight, including darkvision, beyond 5 feet. A creature 5 feet away has one-half concealment (attacks suffer a 20% miss chance). Creatures farther away have total concealment (50% miss chance, and the attacker cannot use sight to locate the target). Also, this storm hampers all movement reducing it by three-quarters. Ranged attacks within the area of the storm are impossible. Spells cast within the area are automatically disrupted.
