You unleash Ithreia’s Blinding Winds, shot through with snow. Creatures in the area are knocked prone unless they succeed at a Strength check against DC 10 + your primary spellcasting modifier. In addition, creatures take 1d6 points of cold damage per caster level. The snow in the area blocks vision beyond 5 feet; targets within 5 feet have concealment and those beyond have total concealment.
