Next you'll say!...

Through subtle perception and a keen mind, once per day you can predict what someone will say next. Using your reaction when an enemy attacks you, you may interject with the line, "Next you'll say..." followed by a line of your choosing e.g. "Next you'll say... You bumbling fool, prepare to meet my blade" the other character must then say that line, followed by immediate shock giving you the ability to take a single attack action or giving their attack disadvantage.

you also gain +1 to your wisdom score.
