Smite Evil

As a swift action, the paladin chooses 1 target in
sight. Add Charisma bonus to attack rolls & add paladin level to all damage rolls against the target,
the bonus to damage on the 1st successful attack increases to 2 points of damage per paladin level. Regardless of the target, smite evil attacks will automatically bypass any DR the creature might possess. Also, while smite evil is in effect, you gain
a deflection bonus equal to Charisma modifier to
AC against attacks made by the target.
