1. This is probably an obvious typo to readers, but I thought I'd mention it nonetheless.

    In Chapter 15, at the top of Page 297 the line reads as follows...

    "For the last attribute, the prefix is shift, the root attribute is spell and the prefix is 1."

    This should actually read...

    "For the last attribute, the prefix is shift, the root attribute is spell and the suffix is 1."

    Happy Coding :-)

    Thank you, I'll get this added to the errata list!
