Grimoire of tiamat

Howdy! Just received my copy of the grimoire of tiamat and I’m eager to dive right in. Have any of you worked through this book and if so can u please share your experiences? Thanks

I really like what Asenath Mason did here in this Grimoire. The Grimoire for me was easy to work with and packed full of very helpful hints, sigils, etc.

What do the spirits in this book do? Is it baneful?

 Well considering the nature and history of the culture traditions that Tiamat is drawn from, some of them can be called upon for baneful workings, yet at the same time depending on how you work with these entities I'm sure that the manner in which events or circumstances are changed or altered in your favor, some may see it as baneful where you may see it as beneficial or helpful in your case.
