Once per game, during the night, the troublemaker can choose to "Stir up trouble." Town will be alerted of this when the day starts. When trouble is stirred up, town can lynch twice that day. Sided with the village.
It's essentially like a gunsmith except with less-opportunity for trolls. I think it can be more townsided in order to give opportunities to lynch CCs, and such.
Still a good role to have.
