One of the most powerful spells that use air against the target is the spell blast vacuum. Similar to the spell chaos bolt, an active pocket of air is sent at the target where it is released, sucking all the air around the target away. The difference between the two, is that the spell blast vacuum creates a much larger and more powerful pocket. When this spell hits the target, the pressure outward from the target is so great that the targets outer skin actually expands, enough that it can be noticed by the naked eye. Blood vessels rupture and can cause open wounds. Some internal organs can also be affected, causing great pain.
