I've really enjoyed this work over the years; it does a fantastic job of creating a practical Goetic ritual structure that can be implemented, understood, and even edited with ease. Many grimoires work with Using Angelic and Sephirothic forces to summon the Infernal, and there are other works that focus on the Qliphothic or Infernal themselves, but it's not often we find ourselves a work that involves using the Qliphoth to invoke Angelic forces, whether their pure form or a Qliphothic abstraction. It holds many experiments in alternate calendars, scripts, and tarot association as well to really "plug and play" for lack of a better term. It's approachable, and yet is very thorough; and in my experience with it, it rewards creativity.
As for the book itself, the construction isn't bad! The gold foiling does fade after time, but this to be expected, though on my copy it started a bit quicker than I had hoped. The covers do "splay" a good amount, and this did also happen rather quickly after receiving this tome; but its still a lovely addition to the bookshelf, and it's faded foiling is only proof its use has been worth it.
