Cunning Killer

You mercilessly dispatch those creatures that you outwit.

Prerequisite(s): Base attack bonus +2, Knowledge (arcana, dungeoneering, local, nature, planes, or religion) 3 ranks.

Benefit(s): When you succeed at a Knowledge check to identify a creature with an Intelligence score of 2 or less, you gain a +1 insight bonus on attack and damage rolls against that creature for a number of rounds equal to your Intelligence bonus. When your base attack bonus reaches +4 and every 4 points thereafter, increase the Intelligence score of the creatures you can affect with this ability by 2 (maximum 12 Intelligence); your Intelligence must exceed the target’s Intelligence by 5 or more for you to gain any benefit. When your base attack bonus reaches +6 and every 6 points thereafter, increase the insight bonus on attack and damage rolls by 1 (maximum +4).
