Focused Disbelief

So certain is your disbelief in the authority of the gods that you can brush aside their spells without effort.

Prerequisite: Divine Defiance.

Benefit: You gain spell resistance equal to 11 + your character level. This spell resistance applies only against spells and spell-like abilities covered by the Divine Defiance feat. You can lower this resistance for I round as a standard action.
