From the introduction: ONE NIGHT STRAHD serves to condense the full campaign experience of Curse of Strahd into a one-shot suitable for Dungeon Masters (DMs) of any skill level. It distills the 200+ hour campaign into a coherent short-form experience that supports three modes of play: • Long Play: Roughly 12 hours, suitable for events such as Halloween. • Mini-Campaign: Roughly 16 hours, generally broken into three sessions. • Stage Game: Variable as needed.
