I've made some pretty substantial changes to the alpha sheets behind the scenes, and to the Pathfinder [Legacy] sheet in particular. Please try clearing your browser cache, or post in the Experimental Features forum if there are any issues!
At this point, we highly recommend that all new Pathfinder sheets be created in the alpha and that existing Pathfinder sheets be copied into it via the 'Copy to Sheets Alpha' link in your regular sheet list
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.
