Overall, I enjoyed this game. It feels very well put together, overall. That said, it's not perfect, so I'd like to share some suggestions.

What Was Good:

• The magic mechanics are just about as perfect as they come. The book's metaphysics are tight and easy to understand.
• This book contains everything I could possibly need to play an intriguing witch, and every single splat appeals to me in some way.
• The tone of the setting, as well, is also excellent. I like how, despite shooting for demonic horror, the game isn't overly Christian in its themes and portrayal. Spirits of all sorts are still individuals, and even the ones that aren't quite as close to being people aren't necessarily evil by default, just weird.

What Could Use Work:

• No table of contents. Fix this immediately so I can find things, please.
• The book really likes to bring up "insanity" a lot. Not to explore it in a meaningful, educated way, but as a spooky setting element. This just isn't all that fun or interesting or, for that matter, respectful to those who are mentally ill in real life. That said, these rules are generally non-intrusive and easy to modify.
• Djinni as a type of witch is weird, and focusing on the wish-granting aspect of djinn is kinda silly. It's still set up in a way that I like on the whole, though, so I'm okay with it.
• Manitou as a word comes from the Algonquin Tribe's belief system, same as the wndigo. Djinn and sosye are both from a still-living religious practice, but Islam, Hoodoo, and their fairy tales (especially the former) are open. The Algonquin People are firmly on the record as CLOSED religions, and so I'd just call these critters something like "animisms."

Aside from that, I have no complaints. Good work!
