Divine Interference (Feat)
You can convert a spell to interfere with an enemy's attack.
Prerequisites: Level 11, Divine Caster Level 10
Benefit: As an immediate action, when an enemy within 30 feet of your space hits an ally with an attack, you can sacrifice a prepared divine spell or (if you are a spontaneous caster) an unused spell slot, and make the enemy re-roll the attack roll. The attack re-roll takes a penalty equal to the level of the spell you sacrifice. You must sacrifice a spell of 1st-level or higher to use this ability. The affected enemy takes this same penalty on all other attacks against that specific ally until the beginning of its next turn.
Special: Whether or not any following attacks are successful, you cannot use this effect on the same creature again for 1 day.
