This book is for the d20 Modern Game, Pathfinder and a few other d20 based games. It presents a generic form of a spellcaster that isn't a wizard, cleric, witch or druid. In a sense it is a throwback to the older "Magic User" class. The basic premise here is to provide full powered (up to spell level 9) spellcasters from D&D like games to your Modern Games. I am not sure how this works out in play, but the concept on it's own is interesting enough. There are new feats and a fun "arcane death" table. Frankly I would like to see that expanded into an "Arcane CSI" to be used in any modern game with magical elements.
