Cold Specialization

At 1st level, a winter witch's mastery of the cold becomes so great that any spell with cold descriptor she casts has its saving throw DC increased by 1. Additionally, all spells with fire descriptor she casts have their saving throw DC decreased by 1. At 5th and 10th level this bonus and penalty are increased by 1, up to a maximum of 3. If the winter witch has a Blizzard Servant (winter child's class ability), this bonus is also added to the DC of her Whirlwind of Hail ability.
