There is a Festival happening in my game soon, and I wanted my PCs to be able to participate in the contests that go along with this kind of party. This is a good move for prolonged contests of strength or endurance like arm wrestling, foot races, or drinking and eating contests. It could be used for something like an archery contest but I might be inclined to write a separate move for that.
It’s Not A Competition!
When you engage in a prolonged contest, roll+STAT as appropriate. The GM will establish a Contest Clock. On a 12+ you win handily and your success may attract useful attention if you wish, on a 10+ you win with minimal effort and may stop rolling, on a 7-9 the Contest Clock advances one segment forward, on a 6- the Clock advances 2 forward. When the Contest Clock runs out the contest is over, and if you didn’t roll a 10+ you didn’t win.
GMs: The more Contest Clock segments you have, the easier the contest will be. I would recommend sticking with 3-4. If you want to make the contest a little more challenging, you can introduce the following wrinkle: You may roll without penalty in the contest a number of times equal to your stat bonus, ie: if you have a +2 STR you may roll without penalty twice after which you take a -1 ongoing until the end of the contest, and possibly for some time after. This represents the character weakening, tiring, or growing sick from food or drink.
