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.
