Black magic

It is mental magic that is created for evil purposes. The black magician uses elementals in combination with mental magic. Curses also fit into a form of black magic thought. The danger of the thought form performed with black magic is that, sometimes, they achieve their objective and destroy, especially when the person to whom it is directed is very susceptible or weak in thought. When it does not fulfill its purpose, that is, it was rejected by the person to whom it was sent, the thought form returns to the person who sent it, what we commonly know as the "rebound", it fulfills its purpose (magic turns against of the black magician) and returns to his place of origin.
