From publisher blurb:
The Respected Class are back again, with another collection of prestige classes for your fantasy D20 campaign, all lovingly handcrafted from the best D20 components and playtested to a fine edge. From Yuan-Ti converts and spies, Bardic College spies, and the Blessed Paladin who embodies the warrior aspect of his deity, be it good or evil, to the Mad Tailor who crafts strange constructs from living things and the Tribal Berserker who becomes a lycanthrope while raging. Prestige classes for every occasion, every class, and every villain.
