Book of Vile Darkness, hardback sourcebook for D&D 3rd/3.5th ed, by Monte Cook.
“Only the most indomitable minds dare to look up the malevolent thoughts and forbidden secrets bound herein. This corrupt tome is filled with deplorable wisdom, malignant ideas, and descriptions of creatures, rites, and practices most foul. Evil permeates every word and image inscribed within it”
-Orcus, Demon Prince of the Undead
“This sourcebook for the D&D game is intended for mature audiences and provides a Dungeon Master with unflinching access to subject matter that will broaden any campaign. Included is a detailed look at the nature of evil and the complex challenge of confronting the many dilemmas found within its deepest shadows. Along with wicked spells, wondrous items, and artifacts, Book of Vile Darkness also provides descriptions and statistics for a host of abominable monsters, archdevils, and demon princes to pit against the noblest of heroes.”
One of the most controversial supplements ever for D&D. Tracy ‘Dragonlance’ Hickman described it as “excrement” and as “cheap, trashy and demeaning.” He stated, “Every dark fear that mothers and clergy across America have about D&D is now, suddenly, true. In one stroke, I watched everything Laura and I had worked toward for the last 25 years come crashing to the ground.”
Admit it, you want to see for yourself what all the fuss was about, don’t you…?
