The targets make a Will save for half damage, but even those who save are still highly affected by this spell. Every victim takes 1d8 points of negative energy damage per caster level (no maximum). Besides the damage, if the targets survive, they are reduced to Charisma 1. This is not ability damage or drain, and only a wish or miracle spell can undo the effects of this spell. To describe their faces would be impossible, but one who sees these creatures after this spell will have a hard time imagining how the victims will be able to eat, see and hear.
