Just save yourself the trouble. When Edward Kelley was trying to figure out pronunciations of the names on the Enochian Tablet and Keys, he accidentally called upon some, and when they learned he called them by mistake, they broke his arm as retribution.
Also, to work with Enochian in any real capacity, you basically have to break a part of your mind to be able to do it. Enochian, while powerful, is batshit as fuck.
