I guess the simple fact that Wardens use them to do just that means the First Law doesn't apply... presumably because a) the magical portion of the attack cancels out the magical defence so that everything is equal after that, and b) because Wardens would be pretty damn useless otherwise.

My game is over, and on a cliffhanger no less!

Finally all caught up!  Great 'casts guys.  Priscellie always sounds too excited to be sitting down!

Great stuff on the 'inconsistency' front too.  Craig, that bit with Murph's ex is at the beginning of Summer Knight if you hadn't worked it out already   ...as an "in" for explaining who Elaine is beforehand, if you see what I mean.

I think I shall forced to watch them all again soon.  Forced, I tell ya!

If his shape-assuming power works on inanimate objects, pretend to be a floor lamp 

Since he can change to look like someone else at will, this could be a perfectly reasonable explanation providing, of course, that he can do furniture

Heh, true

I'm really not sure the circle-around-the-car thing would work.  The whole idea is to insulate the car from the wizard, right?  If you put them both in the circle it won't achieve anything.  The "magic sink" (as opposed to heat sink) would be the better option.

That or having a driver and a stretch limo.  Keep the wizard as far from the most important working parts as possible

Hmm, taking the "static strip" idea, what if you bled the excess energy into a special container, rather than out into the environment.  Kind of like Harry's ring that stores up kinetic energy.  There would be no way to make it perfectly efficient, but you might be able to significantly lessen the effects.  And, as a bonus, you're charging up a magical battery for later!

I was thinking exactly the same thing earlier today!  Just make sure it's away from all the important stuff.  And again, I'd imagine such a 'battery' could attract unwanted attention.

That's true... but if you drove fast enough, or had a long enough 'grounder', it might all be going wrong to someone else behind you somewhere

More seriously, yes, good point
