Halloween costumes (already)

lunapome once suggested using the various deities from the Faerun campaign setting as a Halloween costume theme. I liked the idea, but didn't think about it again until recently, when I looked through the Faiths and Pantheons gallery. And now ... well, now I've decided to do it and the only question is whether I dress up as Mystra or Shar.

I like both of their costumes, and the lovely and talented lunapome is capable of making either one within the next nine months. So, as usual, I'm just feeling indecisive about which one to actually pick.

( pros and cons )

One costume that I have no question about is that ratzeo should be Mask, the god of lies. Because who else should a GM dress up as?
