Black magic
There are four types of magic within the "Slayers" universe: Black, White, Shamanistic, and Holy. Black magic spells, such as the famous Dragon Slave, call directly on the powers of the mazoku and are capable of causing enormous damage. White magic spells are of an obscure origin and are used for healing or protection. Shamanistic magic is focused on manipulation and alteration of the basic elements of the natural world (earth, wind, fire, water and spirit) and contains spells for both offense and convenience, such as Raywing, Fireball, or Elmekia Lance. Holy magic uses the power of the shinzoku, but the aforementioned barrier made its usage impossible for anyone inside before the death of the mazoku Hellmaster Phibrizzo. As a rule, mazoku can only be harmed by spiritual (astral) shamanistic magic, holy magic, or black magic which draws power from another mazoku with greater might than the target.
