From publisher blurb:
A new magic system and spells for old school fantasy RPGs. Based on and expanding Wonder & Wickedness, but still being usable stand-alone, Marvels & Malisons presents five Sorcery Schools:
Apotropaism for protection against the uncanny, inspired by Levantine myths
The Cunning Craft of those pagans out in the country, inspired by folk magic and Celtic stories
Physiurgy for healing and restoration
Arachnomorphosis to tap the power of spiders, and becoming one
Rope Tricks for rope magic ("Knotromancy" is not a real word)
The book also contains tables of random starting equipment for sorcerers for the schools described both in this book and in Wonder & Wickedness, from a spidersilk shirt to your granny's curative oinment, passing by bottled bad weather.
