Death Frost is a direct damage spell with a range of 12" and targets a single enemy model (even a character in a unit). The target unit must pass a Toughness test or suffer a Wound with the Multiple Wounds (D6) and Ignores Armour Saves special rules. This is an Ice Attack. The Wizard may choose to increase the range of this spell to 24". If they do so, the casting value is increased to 13+.
