Zainael is the teacher of witchcraft, to evoke him stand in a circle with a crystal ball and say:
I evoke thee, Zainael, teacher of witchcraft, to appear in front of me in the image of your choosing
Unfocus your eyes, gaze into the crystal ball, and you will see a black cloaked figure holding a great sword
Zainael will give you some tests the following days, so that you may prove that you are worthy of his lessons
