Shadowfrost refers to a type of magic wielded by death knights and formerly by priests. It is a multi-school, combining the Frost and Shadow schools. Multi-school abilities benefit from bonuses that affect any of their schools, use the lowest resistance value among their schools, ignore absorption and immunity effects that apply to only some of their schools, and can be used even when one or more of their schools have been locked with an interrupt effect.
