Failure: The caster is drawn into the Book of the Damned’s demiplane (see the Book of the Damned pages 167–170) and affected by feeblemind (CL 20th); the Book of the Damned is transported to a random location on a random Material Plane world.
The first step in destroying the Book of the Damned is to divide the book into four sections—one each for its daemonic, demonic, and infernal portions, and one for its apocrypha. Separating the book into these four parts is both difficult and dangerous. The ritual requires scrubbing the pages with holy water and reciting potent magical words while reading key phrases hidden throughout the text. Upon the successful completion of the ritual, the Book of the Damned tumbles apart into its four components, each of which must be swiftly separated from the others, for should all four components of the Book of the Damned be within 30 feet of each other at any point in time once 1 minute has passed following their separation, they immediately reform into the complete Book of the Damned as if the quartern disjunction had never been performed.
