From D&D Holmes Basic Set(1977):
HOSTILE/FRIENDLY REACTION TABLE
the party decides to flee they may be able to delay pursuit by
discarding some of their possessions. Unintelligent monsters will stop
to pick up food half the time (roll 1 – 3 on a 6-sided die) and
intelligent monsters will stop for treasure half the time (roll 1 – 3).
Burning oil will deter monsters (referee’s discretion).
actual example of written rules about "what happens when a party
attempts to flee" is quite rare in RPG systems, I must admit, leaving a
lot of us scrambling to patch the hole up with movement speeds and/or
I probably wouldn't run this strictly as-is,
because it's so random(50% chance after all!) but I was still very glad
to see it in print. You can tell players a million times that they can
"do anything," but having something like this written in a book makes it
more real, and also gives people some ideas about how the game is expected to be played!
