How would like some really cool monsters and really cool artwork to with them? Then check Magical Monstrosity Press.
I don’t even remember how I stumbled across this site but damn is it pretty and useful. Nice and simple stat blocks that can easily be used with any retro-clone. Did I mention cool monsters? Yeah, I know I did.
This is definitely one the sites you should keep an eye on for inspiration and really cool monsters.
So there you go. Enjoy!
