Publisher's blurb: In this adventure, the players take part in some spooky local festivities, but when a celebrant takes things too far, it’s up to them to save the town from a dark curse. Luckily for them, the challenges they must face are based on the festival games they have already played, and they will have the aid of enchanted costumes and the valuable prizes they’ve won! The adventure is designed for a party of 4-6 second level characters, but each encounter includes notes on how to adjust the difficulty for more or less powerful groups of PCs. Treat or Trick could take place in any village or small town, such as Phandalin, Red Larch, or even Sloobludop, but if you’re running it as a one-shot, or your players aren’t in or travelling to an appropriate town, the town of Willowton is included.
