Followers of the evil gods, unlike their counterparts who
follow the good gods, are not taught to use magic to heal, but
instead are taught to use their magic to 'unheal', or harm. 
In order to cast this type of magic, one must have no regard
for life, except his own of course. Death and destruction are 
left in the wake of those who practice this dark magic. This
type of magic has such little regard for its target, no reliable
protection from its effects are known.
