This spell is similar to the wizard spell thunder staff, with the exception that the priest needs no material components. Upon completion of the spell, the priest claps his hands together and produces a thundering cone of force 5 feet wide at the apex, 20 feet wide at the base, and 40 feet long. All creatures and objects wholly or partially in the cone incur the effects of thunder staff as printed in the Tome of Magic (pages 32-33).
While the priest must have both hands free to cast the spell most effectively, he can cast it with only one hand. This case might occur if the other hand is bound, missing, or holding a shield, for example. If the caster only has one hand free, he may clap it against bare skin on any part of his body (thigh, cheek, etc.). The resulting cone of force is 21/2 foot wide at the apex, 10 feet wide at the base, and 20 feet long. All creatures wholly or partially in the cone must roll a successful saving throw versus spell. Those who fail are stunned for 1 round and deafened for 1d3-1 rounds (they cannot be deafened for less then 1 round, however). Those creatures who fail are also hurled 2d4+2 feet by the wave of force, suffering 1 point of damage per two feet thrown (damage will always be 2d4+2, even if the creature encounters an intervening surface). If the saving throw is successful, the victim is not stunned, but is deafened for 1d3-1 rounds and is hurled only half the distance. Giant-sized creatures or larger who succeed at their saving throws are deafened but are not thrown, suffer no damage, and are not stunned. If the saving throw is failed, they are hurled 1d4+1 feet, suffer 1 point of damage per two feet thrown, and are deafened and stunned.
Regardless of whether one or two hands are used in the casting, the cone has a Strength of 19 for the purposes of opening doors. It can move objects weighing up to 640 pounds 4d4+4 or 2d4+2 feet, depending on the method of casting. Fragile items must make a saving throw versus crushing blow or be destroyed.
