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.

You can use this ability again on the same creature in future rounds (when you have another immediate action available), but its effects can never stack, even if applied by two different characters with this feat.
