Mark of Ouroboros

A seal of Ouroboros's invention, it infests the bearer's body with his own antibodies. These antibodies run haphazard upon implementation however, and may end up destroying their new host's immunity system, dramatically weakening them, if not killing them immediately. However, if the bearer's constitution is high, and manage to subdue these antibodies, then they will receive the same perk as Ouroboros, and gain an incredibly powerful guard against poisons of all varieties.
