Wife and I just played Part I of the Hunt for Strahd scenario. We got confused by the Strahd tactics. Do you have to defeat Strahd by bringing him to zero hit points? Or do you have to just get him to 5 hit points so he turns into mist form? The directions and tactics really aren’t clear.
For Part II, does Strahd return with full hit points? Or does he just have the 5 remaining hit points from Part I?
