Apostate( Elder Evils, p. 12)
Your hatred of the gods cloaks you with potent resistance against their works.
You gain a profane bonus equal to one-half your character level on saving throws against divine spells. You cannot voluntarily fail a saving throw against a divine spell, even if the spell is harmless.
If you are a divine spellcaster with a code of conduct (such as a paladin), selecting this feat violates your code of conduct regardless of your alignment.
