I'm sorry if I am coming off as difficult. I'm just trying to understand. You say that the mask is connected but any white mask with three spots will work. That confuses me. If the beast is connected to the mask then it should be a specific mask not just anything that fits the beast idea of a skull. I understand that Arachne's need for the mask and cintroll could change in time. Greed and Gluttony and similar but they're not the same you will need to be careful about that. I figured that the blob could change shapes and that the shapeless blot was more it's natural form.
