(General)
You can convert a spell to interfere with an enemy's attack.
Prerequisites
Divine spellcaster,
Caster Level 10th.
Benefit
As an
Immediate Action, when an enemy within 30 feet 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 reroll the attack roll. The second attack 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. Whether or not the second attack is successful, you cannot use this effect on the same creature again for 1 day.
