Duke's X-factor is a bit of a double whammy. On the surface it looks like simple "Truculence" and it does indeed improve his hitting ability and cause some stamina loss to his opponent. But the real gem of this ability is that after the opponent peels themselves off the boards/ice and gets back to the bench, every cringy, regretable or embarrassing thing they have ever done comes rushing back and sends them into a spiral the rest of the game.

Yeah, that one time you told the hot waitress/waiter "You too" when they said "Enjoy your meal!" . . . gonna be like you are right back there again!
