Some final code requests (and screenshots)

Can anyone tell me how to cut the Step Mine MP usage in half? I know that the Step Mine damage is controlled by the number of steps, and the MP it uses also gradually goes up with the steps - but the current MP usage in my mod is far too much since I reduced the damage caused by Step Mine. It causes about 2,500 damage but takes 108 MP (I reduced the damage caused by Step Mine). There must be a byte somewhere the controls this.
