I eventually managed to get them all (playing 8.5c if that's relevant), so it's definitely possible. Whether it's actually worth it is another matter, as it doesn't seem to give you any benefit in the game.I have completed (as far as I know every single character that plays siege, having beat them all multiple times until they tell me they no longer have spirit papers to give me. However, I am still missing 11 of the images, anyone know what causes this? Maybe a possible fix?
