While I love that you've leant into how monstrous afflicted are in their nature with this write, I do have my qualms with certain aspects of the write. This write is far less vague than prior ones, which is a great thing, and I love that you've incorporated guides of sorts to ensure people do not overstep or misuse their transformations. My main issue after reading this through, is the Afflicted's compatibility with deific magics. Prior to this write, the mental changes done to an Afflicted's mind made them in a way almost reject the possibility of higher beings, such as the Aspects or Xan, unless it could be shown to them directly. To now have the magic be compatible with these, while it shows the adaptivity of the symbiote in it's modern era, is rather strange. Adding to this, if an Afflicted can obtain these deific magics, why is it that they cannot obtain varg sigiling? It, in a way, is it's own deific boon based on how it enforces the will to accept Deities in the mind of the Afflicted.
All in all, I love to see this magic getting some attention, and I hope your write is given a fair chance among the others.
