The fighter drops to her knees, her face pale and a bluish cast to her lips and fingers. A cloud of frosted breath escapes her lips as she whispers, "So . . . c-c-cold . . ."

The subject takes 1d6 points of cold damage per caster level (maximum 10d6) and becomes fatigued. A successful Fortitude save halves the damage and negates the fatigue.
