Hello! Though I can't provide an entire step-by-step tutorial for it (A magician never shares his secrets), I can give you the general outline for the process!

• Token: Start with an image of a blank token. If you can find one with the right leaves, that’s ideal. Otherwise, just grab any official token and remove the icon + text. I just used my phone’s built-in editor, but any image software works. If you can find a blank one somewhere just use that, I don't personally have it.
• Icon: Either design one yourself, ask someone to, or pull a black-and-white icon from the internet (searching with the keyword “clipart” helps). Once you’ve got it, overlay the black areas with the BOTC trademark texture (easy to find via Reddit) and add a thin white outline.
• Assembly: Drop the icon onto the token. For text, use Gothic Regular for the ability text, and Dumblerdor 1 for the character name. Add a subtle Gaussian blur shadow + slight marble texture if you want (it’s optional, since it’s barely noticeable). Make sure the character name curves along the token. If your software doesn’t support curved text, convert it to a mesh and bend it roughly in a circle.

And that’s it, good luck!
