Spot Structural Vulnerability
You have an eye for structural flaws and poor artisanship.
Preqrequisite
Engineering 5 ranks, Perception 5 ranks.
Benefit
As a move action, you can attempt an Engineering check (DC = 20 + the item’s level or 25 if the object doesn’t have a level) to identify a flaw in an item or object. If you succeed, you can ignore 5 points of its hardness or treat its break DC as being 2 less until the beginning of your next turn.
