The Groundhog Day Effect in 4e D&D

In the 1993 director Harold Ramis brought us the Bill Murray comedy classic Groundhog Day. For those unfamiliar with this movie, Bill Murray’s character awakens every morning to discover that he’s reliving the same day, February 2, over and over again. After watching the movie again last week I started thinking about how to use the Groundhog Day effect in an upcoming D&D adventure.

I saw this playing out in two possible ways.

  1. The PCs would find themselves in a situation similar to that of Murray’s character in the movie where they actually had to relive the previous day over again.
  2. The PCs had to face the same encounters a second time after defeating them once before.

Both scenarios allow the players to learn from their previous mistakes. How often have you used a daily power in the first encounter and then realized that it would have been more effective against the creatures in the second? How often have you held onto a daily power and then regretted not using it? The same thing goes for actions points.

The Groundhog Day effect, in essence, gives the PCs a do over. Once they realize that they’re facing the same encounter again they can choose to alter their original course of action.
