just fcking swap them with the real thing, sure you gotta be quick but that’s much easier ( dont do that at the same store tho )
or maybe bring a partner, let them hold the real stuffs while you make the fake one, and stay behind after your partner left so you can maintain the fake gold longer and then leave when no one noticed ( some other customers stand in between the camera and the fake gold too )
Well no certainty since ancient and lost magics are archived and most might not be added.
Also it makes sense that life and healing would be virtually identical.
