Disruptive Stance Feat 10
Source Pathfinder Core Rulebook
The slightest distraction can provoke your wrath, and you're prepared to foil enemies' actions.
As long as you are in this stance, you can use Attack of Opportunity when a creature within your reach uses a concentrate action, in addition to manipulate and move actions.
Furthermore, you disrupt a triggering concentrate or manipulate action if your Strike hits (not only if it's a critical hit).

FighterThis indicates abilities from the fighter class.
StanceA stance is a general combat strategy that you enter by using an action with the stance trait, and that you remain in for some time. A stance lasts until you get knocked out, until its requirements (if any) are violated, until the encounter ends, or until you enter a new stance, whichever comes first. After you use an action with the stance trait, you can't use another one for 1 round. You can enter or be in a stance only in encounter mode.
