- The Grand Grimoire of Cthulhu Mythos Magic

I am granting it 5 stars based on it meeting its claims, intentions, and goals. This is intended to be a quality book, to be used as a reference for use of in game magic for the roleplaying game Call of Cthulhu by Chaosium. This book does that. This also has nice bookmark ribbons quality covers, and excellent art, along with useful reference tables, and guides for use within the game.

Well done and well organized. One of the issues I've always had with CoC is the relative paucity of spells and the fact that there was little variety between the various sorcerers in terms of their capabilities. How many times can you describe the effects of shrivel or Voorish sign before there familiarity breeds contempt? (answer: not too many, really). This book not only collects all the various spells, but it also gives suggestions for alternate names and different effects depending on whether the caster is willing to go all out into the outer darkness in preparing the spell. Combined with an excellent introduction and organization of the spells into various types (extend life, offense, protection, summoning, etc.), the book is more than just a 7e update of spells, or even a collection of spells from a variety of sources, but it is also a good way to restore the mystery and danger of spells for any CoC game. I've been using it to rerun Fungi from Yuggoth, and it is amazing how much just a couple of different spells in the hands of bad guys can change the flavor and direction of a story.

I don't tend to buy the newest edition of anything, but this one is worth it. The cleanup of the rules has been so worth it. Better explanations, faster game play, and good consolidation of skills. This really is one of the few times paying the extra money for the next edition was worth it.

I *love* this thing! While I've been playing RPGs since the 80s (don't judge), I'm relatively new to Call of Cthulhu, so when I saw that the Grand Grimoire was a "thing" I was immediately intrigued. The spells in this thing are collected from years of CoC products, old and new, with the particulars of each one updated for 7th Edition. Each one of the spells in this thing is so evocative that it will, in and of itself, inspire you to whip up a horror scenario based around it. It's going to go quite a long way towards adding creepiness and depth to the CoC games I run. I'll also mention that the printing quality, binding, excellent paper, and so forth make you feel like you're getting your money's worth. And if anyone asks, I have not noticed any particular modern-day political bent to the book's contents.

Nice long read and many spells and information that can be used in other games like dnd

This is a great supplement for anyone looking to add a more spells to their game. The book is well organized, and splits the spells based on the kind of spell it is i.e. banishment, combat, enchantment etc. The book also discusses things such as spell components, ley lines, phases of the moon, and other astronomical factors. If you want to make the magic in your campaign feel more lovecraftian this is a good resource. I also enjoyed that they added a couple of creatures, and NPC's interspersed between the spells. Not many, but it was unexpected and a nice touch.

Great!

easily my favorite addition to my CoC games. basicly Its a refrence book, if you're looking for anything other than that, than this is not the supplment for you. If you are, than this is by far the best source for CoC magic. There are a few contridictions between this book and the Keepers guide - I tend to stick closer to this one, but honestly that's just a personal prefrence and the diffrences I noticed are very minor (e.g. taking d6 or d10 sanity from casting a certin spell) It is not a 'must have', but it makes a great addition

If you're looking for the thing that is going to spice up your games, this is the book. If you don't understand the magic of hpl and you need some insight, this is the book. If you want a nudge further down the rabbit hole of the Cthulhu mythos, this book will help you get there.

I am a regular keeper for multiple Call of Cthulhu player groups. This book is extremely good for direct information about spells and magic etc., but is also very useful for inspiring ideas and themes of my own. It is very worthwhile as a keeper. As an investigator player it might give too much information....but then all informative book would do that, really. An excellent book.

Livro adoravelmente magnífico! Ilustrações muito boas e possui todo tipo de magia para acrescentar nas aventuras e criação de cultos para aventuras do Mythos!

Excelente libro, cómo siempre es una delicia visual, pasta dura, gráficos, toda una gama de magia y conjuros para el mejor juego de rol :)

So. Much. MADNESS!
