/* 
	Book of Vile Darkness: This is a work of ineffable evil—meat
	and drink to divine spellcasters of that alignment (LE, NE, CE). 
	To fully consume the contents requires one week of study. Once 
	this has been accomplished, an evil spellcaster gains a +1 
	inherent bonus to Wisdom and one experience level—receiving enough
	XP to put the character’s XP total midway between the minimum
	needed for his new (higher) level and the minimum needed for
	the level beyond that.
	All lawful neutral, neutral, or chaotic neutral characters who
	touch the book take 5d4 points of damage, and reading its pages
	causes them to become evil (Will DC 13 negates). Such converts
	immediately seek out an evil cleric to confirm their new alignment
	(with an atonement spell).
	Divine spellcasters neither good nor evil (LN, N, CN) who read
	the book either lose 2d6×1,000 XP (01–50 on d%) or become evil
	without benefit from the book (51–100). Good divine spellcasters
	(LG, NG, CG) perusing the pages of the book of vile	darkness have 
	to make a DC 16 Fortitude save or die. If they do not die, they 
	must succeed on a DC 15 Will save or suffer from a continuous 
	confusion effect (per the insanity spell). In the latter event, 
	even if the save is successful, the character loses 20,000 	XP, 
	minus 1,000 for each point of Wisdom he has. (This calculation 
	cannot result in an XP gain.)
	Other characters of good alignment take 5d6 points of damage from 
	just handling the tome. If such a character looks inside, there is
	an 80% chance that an evil outsider attacks the character that 
	night.
