This powerful spell is invoked primarily against invading armies or in siege warfare. The spell's primary effect is to destroy troops or fortifications of creatures who have done unredressed damage to a priest or his companions. The spell begins with the priest describing the atrocities an army or band of marauders is guilty of. The priest must have first-hand knowledge of these crimes, or must have heard testimony from a witness under the effect of a zone of truth or true speak spell.
The spell strikes as a great column of force that descends from the sky. The area of effect is a circle whose radius is 5 feet per level of priest. All creatures within the area of effect take 1d6 HP per level of priest in damage. Creatures making a saving throw versus spell take half damage. Small objects must save versus crushing blow or be destroyed. Structures suffer damage as if hit by a heavy catapult (2d12). Any creature unfortunate enough to be flying over the area of effect takes 1d6 points of damage for every 10 feet above the ground the creature was flying to a maximum of 10d6 plus the normal damage due to the crushing blow of the spell.
When cast over water, the spell raises a wave 10 feet high per level of the priest, travelling 30 feet per minute in a circle that grows outward from the area of effect. On land, the force of this spell often crushes trees and rends the earth producing a great cloud of dirt and dust, obscuring the area for 1d4+1 rounds.
The material component of this spell is the priest's holy symbol and a war hammer which the priest throws into the air as the spell is cast. The hammer is destroyed in the casting.
