Does anyone here have any practical experience with the Grand Grimoire? I'm interested to hear the experiences of others. I'd also like to politely ask to please keep the responses on topic. I don't mean to come off as rude but I've found that many threads here start out on topic while on page one, but as early as page two it's as if I'm reading a whole new thread. While I'm sure your experience with another grimoire or book may be useful, I'd like to keep it focused on the Grand Grimoire please. Again, I don't mean to sound coarse but I don't want to read through several unnecessary posts just to find someone who actually does have experience with this tome. Thank you for your time.
