You can befuddle a foe by striking a blow after tumbling.
Prerequisite(s): Amateur Swashbuckler feat or panache class feature, Canny Tumble, Acrobatics 7 ranks.
Benefit: When you use Acrobatics to move through an opponent’s threatened area or space without provoking an attack of opportunity from that opponent and then hit that foe with a melee attack in the same round, as a free action you can spend 1 panache point to deny that foe its Dexterity bonus to its armor class until the end of your next turn.
