You have mastered techniques to take advantage of every drop in any enemy’s guard, gaining the following benefits: - When you hit a creature with an [[Opportunity Attacks]] the creature’s [[Movement and Position|Speed]] becomes 0 for the rest of the turn. - Creatures provoke [[Opportunity Attacks]] from you even if they take the [[Disengage]] action before leaving your reach. - When a creature within 5 feet of you makes an [[Attack]] against a target other than you (and that target doesn’t have this feat), you can use your [[Reaction]] to make a [[Attack|melee weapon attack]] against the attacking creature.
