When someone targets you with a spell that seeks to erode your willpower, you steel yourself against the attack.

<php>echo “<b>Prerequisites:</b>”;</php> Concentration 3 ranks
<php>echo “<b>Benefit:</b>”;</php> Any time you would be required to make a Will save, you can use this maneuver as an immediate action. Roll a Concentration check instead of the Will save and use the result of that check to determine the save’s success. You must use this maneuver before you roll the Will save. A result of a natural 1 on your Concentration check is not an automatic failure. You gain one additional use of a maneuver per encounter.
