I assure you, hitting things with Ka’vil is not the proper use of it. There are some people that would be fairly aghast at that use of it, really. That said, it’s a very handy side-effect of what it is that it’s fairly close to Immutable, and while red ethereal constructs are pretty close to real, they are not quite.

Nathan ends up hitting things with it fairly often, given that he his preferred magic does not have the fastest evocation speed. Fortunately, it’s really pretty good at hitting things, though I imagine that Nathan is rarely trying to hit highly stable and very murderous constructs with it. Hmmm. Scratch that. That probably happens to Nathan on a somewhat regularly basis. There is a reason Peter feels justified in blaming this on him.
