Blessing of the Cerebral Infestation

An intangible mind worm arcs through the brains of 3 creatures within range. They must succeed on an intelligence saving throw, taking 3d6 psychic damage on a failed save. Additionally, the next time the creature would make a saving throw within 1 minute, roll a d4 and subtract the number rolled. Targets that succeed take half damage and suffer no additional effects.

This spell has no effect if the target has an intelligence score of 3 or less. 

This spell may be cast at higher levels, increasing the damage by 1d6 per spell level above 3rd.
