Your melee caster check deals 1d6 points of nonlethal cold damage + 1 point per level, and the target is fatigued. The fatigued condition ends when the target recovers from the nonlethal damage. This spell cannot make a creature exhausted even if it is already fatigued. You can use this melee touch attack up to one time per level.
