The sure brilliance of this idea is too good to NOT let it work.
I'd agree that deciding ahead of time to let it work once isn't that good of an idea. Ruling at the time that a clever idea works, and then realizing that it shouldn't have, is something a bit different. (Just let the players know!)The worse option IMO, however, is to knowingly let it work once and then not again. That's a really bad precedent to set and a terrible suggestion. If the spell works one way one time, it should work that way all the time.

I have to say, I've never seen cats take much interest in mirrors.For something even closer to the potential effect of the spell.. put a cat in front of the mirror and watch the cat go nuts trying to kill the intruder.
That's because most of them don't like seeing other cats stare at them. So they try to reduce the 'friction' by looking away. But force a cat to look into a mirror.. they start acting funky.starwed said:I have to say, I've never seen cats take much interest in mirrors.
