I ran a one-off Halloween adventure for my players this past weekend. However, they didn't use their own character, instead they got to choose from a roster of pre-gens I created for the occasion. The options were: Ash Williams (of Evil Dead fame) Count von Count (of Sesame Street fame) Edward Scissorhands Elvira, Mistress of the Dark The Scarecrow Van Helsing The characters all had the same basic stats, but they each had unique powers as well. The mission was to clear out a haunted house where the props had come to life, and rescue the children trapped inside. If they were successful, the players would get to roll on a table of Halloween-themed rewards, which they could then bring back into their "live" campaign for their real characters to use. I forgot to get screen shots while the adventure was underway, but here's a sample of the carnage they inflicted: At the conclusion of the adventure, the characters were thrown a pizza party by the Pumpkin King and Queen, while the players rolled for the Halloween rewards on the rollable table. Here's a screen shot from that: This was my 3rd year to run a Halloween-themed adventure for my players, and a good time was had by all!
