In a bar not too far off the road, a man walks in. his boots clattering on the wooden floor. The bar is noticeably empty with only a few guys still around either drinking or chatting. Not too surprising since it is already the evening and they probably went home. The smell of smoke and liquor still hangs in the air like a fly caught in a web. The man in the trench coat pulls himself on a stool near the counter. His face covered by a bandanna and the brim of his hat obscuring the view of his eyes. The bartender, who had been cleaning a beer glass, looks up.
"So what'll it be, stranger?"
The man responds in a gruff and tired voice. "Dark and Stormy."
An alchemist enchanted his equipment to produce even more powerful alchemical compounds, potions and the like. Unfortunately, it is not well-known that he had different sets of equipment for different processes: If the wrong set of gear is used, the result will invariably fail to function. It's not a cursed item, just something that's hard to figure out.
