How exactly does this spell work? The Drain is (Damage Value - 6). What does this mean? If I have 9 boxes of Stun damage, the drain is 9-6=3? Or does it mean the number of hits you get on the test - 6 is the Drain? Force has nothing to do with the Drain? If not, why would you ever cast it at a Force less than twice your Magic? If the Drain is based on the number of boxes of damage you currently have, how does that interact with Preparation? If you prepare a magical slap patch of this, what sort of Drain are we talking? Since you weren't injured when you prepared it, does that mean there is 0+2 Drain(the +2 is from Command trigger)?
