Benefit

As long as you have an enchantment spell of 3rd level or higher available to cast, you can cloud the mind of a creature within 30 feet as a standard action. The target takes a -2 penalty on its next single attack roll or Reflex saving throw. If the target makes no attacks or Reflex saves within a number of rounds equal to the level of the highest-level enchantment spell you have available to cast, the effect ends. Multiple uses of this feat don't stack. This is an enchantment (compulsion), mind-affecting effect. As a secondary benefit, you gain a +1 competence bonus to your caster level when casting enchantment spells.
