flee
Once initiated, after some rounds of combat you will escape the room in a random direction.

Note, stacking the flee command will increase the number of rounds you remain trapped in combat.

flee stop
This will still any attempts at fleeing, or generally leaving the room while engaged in combat. For example, if you accidentally type south while in combat, you can use flee stop to remain where you are.

You can also start fleeing just by typing direction you want to flee to, but that won't be as fast.
