Libram of Ineffable Damnation: This mystic book is of great value to arcane spellcasters of evil alignment (LE, NE, CE). Study of the work requires one week. Upon completion, the evil arcane caster gains a +1 inherent bonus to the ability score controlling his or her arcane spell-casting ability and experience points sufficient to place him or her halfway into the next level of experience. (If the reader has levels in more than one arcane spellcasting class, he or she must choose one of the classes to be affected.) Nonevil arcane spellcasters (LN, N, CN, LG, NG, or CG) are permanently drained of 1d4+1 points of Constitution and must atone (see the atonement spell) in order to gain any further experience. Anyone incapable of casting arcane spells who reads even a single word of the work must make a Will save (DC 20) or suffer insanity (see the insanity spell). Except as indicated above, the writing in a libram of ineffable damnation can’t be distinguished from any other book, libram, tome, or so on until perused. Once read, the book vanishes, never to be seen again, nor can the same character ever benefit from reading a similar tome a second time.
