As much as I think the rules in this supplement are good, the example spells are not. I did not get Forbidden Magic for evil spells, I got it for those that are beyond human ken. Those that have flaws because of an incomplete understanding of the methods and basis for the spells' magics. And the spells section is all evil spells.

So if you want evil spells that will corrupt or destroy the characters, this is for you. If you want other forms of forbidden magic, well the rules will help you design your own.
