wimpy [percent]% wimpy [hitpoints]
This command allows you to choose a point at which you will flee from combat automatically. This is a critical setting, it can save you from death if you are disconnected or not paying attention!
You can specify a percentage of your hitpoints by giving the command a number, and following it with a "%". Otherwise, the number you give will represent a number of hitpoints. Passing no argument will show you your current hitpoint setting.
If you don't set your wimpydir, you will run to a randomly picked exit. Mercenaries get notified which way they wimpied.
