Shadow Master

You have somehow transferred your soul into your body and now have your shadow under control.  Your shadow can attack others shadows using the same weapon you are holding.  If your shadow attacks your opponents shadow, inflict the damage done to the owners shadow. Your opponent's shadow cannot attack back unless they too have the 'Shadow Master' feat.  Starting at 5th level, you have the ability to control your opponent's shadow as well, if your combat is in a place where you can see your opponent's shadow, for example against a building in the middle of the day.  Controlling your opponents shadow decreased their walking speed by 10, and for each 5 levels it increases by 10.  In addition, your opponents shadow can attack the owner of the shadow with one of his or her weapons.  Doing so acts as the controlled shadow being part of the battle, so the shadow has its own initiative.
