Snagging Strike [one-action] (Feat 1)
Fighter
Requirements You have one hand free, and your target is within reach of that hand.

You combine an Attack with quick grappling moves to throw an enemy off balance as long as it stays in your reach. Make a Strike while keeping one hand free. If this Strike hits, the target is Flat-Footed until the start of your next turn or until it’s no longer within the reach of your hand, whichever comes first.
