Confounding Tumble Deed

This is a Panache — a class feature gained through that class's own talent choices, not a feat you pick through normal feat selection.

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.
