Level 3

Level 3 deals with much bigger threats than the other two levels before it. The host as well as the surrounding area will most likely be changed to fit better to the invader's criteria of survival. Some will not even notice their Infestation as these creatures are seen to be more secretive with their work. They will actively try to change their host's mentality, behavior, and surroundings to get to their goal

Walking hives are much more common, so are the observation of more obscure symptoms like neglect of hygiene. While each symptom could appear in every one of these levels, this is where they start to get more...unique so to speak. From here on out, I suggest only reading onwards if you can handle these sorts of things
