This book is all about how to make a good alignment mean something, and how to live up to the ideals implied in that alignment. The Book of Exalted Deeds is intended for mature players because it deals with tough questions of ethics and morality in a serious manner. It's intended to help players and Dungeon Masters wrestle with hard in-game issues: Is it okay to slaughter every drow I see and sell their goods on the open market? How do I wrest information from enemy prisoners without compromising my alignment? Is there any hope for the orc whelps in the stronghold, or should we slaughter them, too?
Many players would just as soon overlook these questions, believing they detract from the fun of the game. There's nothing wrong with that. For groups that want to address these issues, however, the Book of Exalted Deeds opens the way. At the same time, it presents a whole host of new opportunities for player characters of good alignment and righteous conviction: new feats, spells, prestige classes, magic and mundane items, and rules to help address the situations they face. Characters of all classes can benefit from the new material in the Book of Exalted Deeds -- if they are willing and able to walk the straight and narrow path of the exalted.
