get meat parasite in deserted base, then go to science lab in new ark to get it removed. wait a day or two, then go back to the lab to find that it is infested, then go to deserted base, fight mistyra and win, then ask her to help with the lab. then explore a ton (get all the chests in there), go to the top floor, then fight the meat core, go back up from the sewer, go to lab and uhh... this is taking longer than expected... After all this go to the deserted base, and uhh... you'll get the rest (strength/mys 4+ needed here)
