This rituals are quite simple and the result is satisfactory. Personaly I have used a more direct technic to work with this forces. If the practicioner have the experience to do an evocation to one of the 50 names of Marduk, then perform it. Then, it will be a lot simpler to work with the forces mencioned there. Just one last comment, do not use the direct practices of the Necronomicon (the main Sumerian book from wich this one has been extracted) to summon this forces if you are not very well prepared to. Danger is real. To replly to this review, please e-mail me to varcan@hotmail.com
