One of my main goals with Flex is to encourage all types of gamers. I want the super creative types to be able to use Flex as an outlet and I want the power gamers to enjoy the tactical combat. In Flex, I think we’ve achieved this with the Stunt system.
Stunts are improvisational actions every player make once per turn to assist another player. You cannot perform the same stunt twice within a combat. To perform the stunt declare what you want to do. Then the game master decides what trait is most appropriate to the action. Finally you roll the action dice you wish to devote to the stunt plus an appropriate amount of trait dice. All of your hits are awarded to the action you wish to modify.
Because the bonus you give is related to your traits players want to leverage their highest stats. A strong character will stunt to knock enemies off guard by throwing chairs at them or shoving them while a wise, magical character may use their magic to set an allies sword on fire for the attack. This creates very memorably combat that encourages role-playing and the fact that Flex is extremely deadly unless players work together with stunts encourages the roll-players.
Overall, I love the stunt system and I’ll probably find a way to get it into every other tabletop system I play.
