Just as a mage needs to believe in the power of his in­ struments, he must also use his practice in order to craft a Wonder. Dr. Hans von Roth would use craftwork and weird science to make his Devices; John Courage employs hypertech to craft his special weapons; Jennifer Rollins incorporates a mixture of gutter magick and witchcraft into her artwork, while Jodi Blake combines maleficia with the Art of Desire in order to shape Wonders that entice people into sin. A mage can’t make Wonders while using a practice he doesn’t understand – that would be like trying to build a 3D plasma-screen TV when you don’t even know basic electronics.
