Exploit Weakness (Ex)
Replaces: Brawler’s Strike
At 5th level, as a swift action a steel-breaker can observe a creature or an object and find its weak point by succeeding at a Wisdom check, adding her brawler level as a bonus on the check, against a DC of 10 + either the object’s hardness or the target’s CR. If she succeeds, the steel-breaker gains a +2 bonus on attack rolls until the end of her turn, and any attacks she makes until the end of her turn ignore the creature’s or object’s DR or hardness.
A steel-breaker can instead use this ability as a swift action to analyze the movements and expressions of one creature within 30 feet, granting a bonus on Sense Motive checks and Reflex saving throws, as well as a dodge bonus to AC against that opponent equal to 1/2 her brawler level until the start of her next turn. This ability replaces brawler’s strike.
