"So we can't just kill them?"
Sometimes a knockdown, dragout fight can be dull. Sitting around waiting for your turn to roll a die turn after turn isn't fun. This generator helps the Dungeon Master to come up with ideas to keep things fresh and to give players exciting goals in addition to staying alive.
To use this generator, consider the combat encounter you were about to throw at your players. Now run the generator and see if it inspires a more creative approach to the encounter.
