Both the host and the parasite has the same Nutrient Priority. It makes you think of a way of how you'll get more nutrients than the host (May it be the species host, or an organism host).

Are complex creatures too advanced for you to understand? Well, let me flood you with them.
This is still available before unlocking Nutrient Priority. Can be misleading for someone that likes to do things in order. I was on it for a few days and couldn't get past 450 hrs.
