Evil Arm of Hextor

While the Hextorians are all very fond of battle, sometimes there are armies just too big to defeat with available forces. For such armies the priests of Hextor use his evil arm, which robs the priests’ enemies of all hope and desire to continue moving against the forces of Hextor.
The spell is cast initially around a brazier specially prepared by the priest. In the brazier are 1,000 gp worth of special incense, which are burned during the casting. The smoke produced in the braziers grows and thickens, forming into a great arm of black cloud, which ends in a sinister hand. This arm-like black cloud climbs through the sky, heading slowly towards the target military force, which may consist of up to 20 creatures per level. When the shadow of the arm’s hand falls upon the target force, all individuals within the force must make saving throws versus spells.
Everyone who fails their saving throw is affected by the spell, and must immediately halt movement for the day. These individuals will refuse to march into battle, and argue and bicker with one another. Every day after the first day of being affected, another saving throw versus spells is made by all of the individuals still under the influence of the spell; three consecutive failed saving throws in three days indicates that outright battle has taken place among the discordant troops.
