    Gorgeous

    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.

    A damn good book.

    Posted by Unknown on 20th Sep 2017

    + 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

    great compendium

    Posted by J S on 30th Jul 2017

    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.

    My god, it's full of (black) stars

    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.)
