====Chink in the armor====
: As a standard action, you may study the armor of an opponent to find a weak spot. You must beat your opponent Wits with a Feint check. On a successful check, you have found a weak spot. On a failure, you did not find anything. This check is made only once in combat.
: If you found a weak spot, you can make a feint attack to try to hit the weak spot for the whole combat duration. Your opponent Defense is increased by the same amount as his damage resistance from his armor. If you hit the opponent, you ignore the damage resistance of the armor when rolling damage.
: This feat can only be used against artificial armor. You cannot use this skill to bypass natural armor or damage resistance given by spell or feat.
: '''Specialist:''' Your attack to bypass an armor is not a feint attack, it is a normal attack.
: '''Expert:''' Your opponent Defense is not increased by the same amount as his damage resistance from his armor.
: '''Master:''' Studying an opponent is an instantaneous action.
