For example... if I kill someone with a fireblast, that's lawbreaking. If I blow someone off a building with an air blast, that's lawbreaking.

But if I set a building on fire, but the fire itself is nonmagical, and THAT ends up killing someone a few minutes down the road, is THAT lawbreaking?

This is purely supposition, but I always thought this was why Wardens carried swords: mundane killing is A-OK, magical killing is not.


With regards to wards, couldn't the ward be keyed to intent or action? For example: if someone was trying to break down your door (as opposed to just knocking on it.) Otherwise wouldn't Harry have vaporized any door-to-door sales people or the like before now?
