Alpha sheets can now be added to games via the edit option in the alpha sheet display. In addition, statblock embedding should also work for the [sb=show][/sb] tags. Any problems, please post in experimental features with links to the sheet and the game.
I made it with this tutorial, though I didn't do everything his way.. I can't use the pen tool the way he requires and I wanted a transparent background. I think I'm going to try doing another version with better wings.. that's the part I'm least satisfied with.
