Cure flask icon empty.png This trait has not been fully evolved, thus making it a stub. You can help make it useful by expanding it.

This achievement is exclusive to the Shadow Plague DLC. This is unlocked by evolving the symptoms Anabolic Boost and Pheromone secretion.


Anonymous: I had to also evolve Muscular Hypertrophy in addition to Anabolic Boost to get this achievement. This is the path of least DNA:

  • Shadow Blessing > Nocturnal > Steroidal Boost > Pheromone Secretion > Anabolic Boost
  • Photophobia > Hyperdontia > Jugular Bite > Shadow Slaves > Muscular Hypertrophy

It sometimes takes a long time for the achievement to appear even after you have these two symptoms evolved.
