I am more in favor of adding an ability to the quarter-staff which allows you to beat people over the head (knocks them out) if you attck their heads from behind, allowing you to mug them (and potentially anyone else near by the same fortune you would get.) This ability would be automatic when used from behind and its chance of success would be based on your Steal skill.
If that were implemented, however, I would write the mug function out of the mod... or make it only useable on players that are #sleep, #meditate, #knockout (the theoretic name for the quarter staff hitting you on the back of the head.)
