You gain a sacred bonus to your attack and damage rolls equal to one-third your caster level against dishonorable opponents (maximum +5). This opponent must in the current encounter have attempted a dishonorable attack. Dishonorable attacks include all ranged attacks, sneak attacks, ambushes, poison use, subtle magical attacks (subject to GM adjudication), or attempted an attack while you are helpless, surprised, or massively and obviously outclassed (CR is 7 or greater than your current character level, etc.).
