Talal’s work comes with black magic protection from any kind of new attempts of black magic. Witchcraft, Wicca, voodoo, curses, hexes, dark magician spells, love voodoo are some of the most common spells of magic to name a few. As long as you don’t do black magic to someone else or intentionally accept it, then you cannot have it again and will not  be looking to get rid of demons again. In general, a victim of black magic would have no intention of either.
