The ability to find weaknesses in an opponent, places where one can strike to greater
effect. Higher levels of ability in this skill allow you to find weaknesses in more
difficult targets and reduce the amount of time you need in order to find a weakness.
You will continually attempt to find weaknesses in your opponents in combat, and you
can look for weaknesses outside of combat simply by closely examining someone.
