Finally got the Monster Creator all nice and spiffy. Again, thanks to Thread Of Fate for providing a great structure to build upon. I'm willing to listen to feedback, and constructive criticism!

I do plan on building a bestiary with this thing, starting with a bunch of level 1 critters, and I'll share what I make. (I'm currently just banging rocks together making these things, so please don't expect too much, and don't be afraid to make edits to better suit your players.)
