Dislocate (Ex)

: A ninja with this trick can dislocate most of her joints and bones at will. She makes two rolls when making Escape Artist checks and takes the better of the two rolls. If she already rolls twice while making an Escape Artist check because of another ability or effect, she gains a +2 insight bonus on both of those rolls instead. If the ninja is under the effect of a spell or ability that forces her to roll two dice and take the worse result, she only needs to roll 1d20 while making Escape Artist checks. If the ninja fails an Escape Artist check by 10 or more, she suffers hp damage equal to the check’s DC/5.
