Mafia 100. Sylvan: Tree of Life.

Yashur, consider that both roles had no defense, and the city won because the elf moves first. Or, there were 100% defenses that they broke that night, and the next day, the Heroist was executed.
In fact, this is the only time in the game when percentages mattered. I don't count the defense of Mourne; Ples still survived.
