Ataf
Ataf: An evil angel named in the Sword of Moses.
The magician is supposed to invoke this being, along with several others, in order to separate a man from his wife. In addition to striking the magician's enemy so that his family is sundered, these angels are also said to preside over a variety of disorders, including pain, inflammation, and dropsy, a condition associated with heart disease.
