Aura of Winter's Wrath

The Frost Sorcerer creates a magic ball of ice pushing the feeling of an Arctic Breeze into the air around target point for up to 20 feet, depending on the strength of the Sorcerer.  All entities within the range of the spell must perform a Constitution save, otherwise a layer of Frost deals a continuous 1d6 Damage per turn for the duration of the spell or half on succesful save
