By calling upon his deity, the caster of a spiritual hammer spell brings into existence a field of force shaped vaguely like a hammer. As long as the caster concentrates upon the hammer, it strikes at any opponent within its range, as desired. Each round the caster can choose to attack the same target as the previous round or switch to a new target that he can see anywhere within his maximum range. The spiritual hammer's chance to successfully hit is equal to that of the caster, without any Strength bonuses. In addition, it strikes as a magical weapon with a bonus of +1 for every six experience levels (or fraction) of the spellcaster, up to a total of +3 to the attack roll and +3 to the damage roll for a 13th-level caster. The base damage inflicted when it scores a hit is exactly the same as a normal war hammer (1d4+1 points on opponents of man size or smaller, or 1d4 points on larger opponents, plus the magical bonus). The hammer strikes in the same direction as the caster is facing, so if he is behind the target, all bonuses for rear attack are gained along with the loss of any modifications to the target's AC for shield and Dexterity.
As soon as the caster ceases concentration, the spiritual hammer spell ends. A dispel magic spell that includes either the caster or the force in its area of effect has a chance to dispel the spiritual hammer. If an attacked creature has magic resistance, the resistance is checked the first time the spiritual hammer strikes. If the hammer is successfully resisted, the spell is lost. If not, the hammer has its normal full effect for the duration of the spell.
The material component of this spell is a normal war hammer that the priest must hurl toward opponents while uttering a plea to his deity. The hammer disappears when the spell is cast.
