i purchasedthe grand grimoire a few weeks back. If anyone knows about it, they will know how dangerous it is is. but even if someone was an extremley advanced sorcerer, would you recommend them practissing it?
The Grand Grimoire - or any grimoire - I don't recommend for any diligent sorcerer. The book is so pathetic it teaches you to sell your soul to goetic demons; which in truth are more like slaves created by mankind rather than Gods of the psyche.
Get started with the foundations of magic first then consider the Grand Grimoire (by then you'll scoff at it anyways).
