Firestorm

Firestorm is a multi-school magic, combining the Fire and Nature 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.
