Oh, right, it could be that! That sounds like a weird difference to have, but also kinda neat!

I guess it would've been useful to have something like that back when I was in magic school. It would've saved me a lot of times getting caught, that's for sure! Ah... Considering what I was usually up to, though, I might've set it on fire by accident or something, so maybe it's for the best that I didn't have one!
