An amazing book that takes you deep inside the magic of Cthulhu. I would say a must buy for both players and Keepers alike. The seasoned investigator ??♂️ might use spells ? by now, and also be able to identify many of the foes’ spells. For the Keeper this book ? offers a deep ocean ? of gothic magic that you can throw into your campaign and at the players. Beautiful artwork and high quality book bind. Warmly recommended. ?
This is an amazing supplement (gorgeous art, great spell desciptions) and exactly what I wanted; however, the book is deteriorating faster than an actual handwritten tome of antiquity. The binding has already separated, and I'm afraid that within a few more weeks it will have the pages falling out entirely. Worth the purchase, but handle with care.
Pro: Enough magic for all your investigators to go properly insane and become cultists. Probably more than you'd ever need and very helpful accessoire for writing scenarios yourself. Neutral: A few illustrations for ritual drawings and inscriptions would be nice. Con: Would definitely benefit from a different structure (not just everything in alphabetical order but sorted by categories).
Maybe not an essential CoC supplement, but honestly, a Keeper should buy it even if they're only going to lovingly turn the pages and think of horrible ways to mess with their players. TGGoCMM is an unparalleled resource for magic in CoC. Just buy it.
This is a beautiful book that could have been just as useful as a simple list of spells like many other companies produce. Chaosium made a real gem here, beautiful to look at as well as being a wealth of fun ideas to use at the table. Must have book.
+ Exhaustive content. Plenty of spells, rituals, potions, ect all. + Solid production values. Full color. Good art and page layouts. +/- Some new systems but could have been further developed. - Everything is lumped together alphabetically. Some separation say between Rituals, Spells, and Item Creation would be helpful, or at the least, some separated indexes. - A listing of all mythos tomes would have made sense to include
all the dark and obscure mythos-magic you could ever want! page directions among the spell categories (chptr 3) is the only thing i feel is lacking. or even better - sort everything according to category instead of alphabetically.
Gorgeous design; cool little alternate rules like folk magic, ley lines, and spell components; and, of course, scores of awesomely dreadful spells drawn from the history of CoC. (It also makes a fun summer read in the park, but beware picnicking families carrying Elder signs.)
