You know the situation: the players have decided that splitting up is a good idea. Maybe they’re on a shopping trip, maybe they’re investigating a dungeon/mothership, maybe some of them were arrested.
What’s the best way to handle the situation outside of combat? How do you keep it interesting for the players, while moving the story forward?
“Don’t split the party” is mostly just a warning to players that I’m not going to lower the difficulty of the encounters just because half of them decided to wander off.
