Action Before Thought

Your supreme sense of the battlefield, unmatched
martial training, and simple, intuitive sense of danger
allow you to act faster than the speed of thought.
You can use this maneuver any time you would
be required to make a Reflex save. You roll a Concentration check instead of the Reflex save
and use the result of that check to determine the
save's success. You must use this maneuver
before you roll the Reflex save. A natural 1 on
your Concentration check is not an automatic fail.
