Both FieldCraft and its companion title, WoodCraft, assume a certain degree of magical understanding on the part of the reader with regard to routine divination, spell and Circle casting. For this reason the text does not include the basic elements of rudimentary witchcraft that can be found in titles similar to Mean Streets Witchcraft and Sea Change. The books have been written in tandem to avoid any unnecessary repetition, and to provide cross-references where necessary.
