My heroes finally used the purple drank in quest 11 when facing the Gargoyle. Unfortunately the Gargoyle also was stone and not activated, and it was just the barbarian separated from his group significantly by 5 turns or so. He already had 6 defend dice, so figure it was not super useful on him compared to say, the wizard using it last minute to cheat death.
Anyone have an epic story of how their group used this liquid?
