Monster Hunter Training

You are skilled at fighting monsters. Due to your knowledge of fighting creatures that commonly use natural weapons, size, and more bestial tactics you have recognized trends in how to avoid hard from them and how to strike back effectively.

When fighting creatures that attack using natural weapons such as claws, bites, tails, wings etc... and they do not have advantage to hit you you may add your proficiency modifier to your Armor Score.  This ability is lost if the creature gains advantage on you, you are hindered in your movement by difficult terrain, restrained or otherwise limited in mobility.

Additionally, as a bonus action you may make a Knowledge Check (Arcana, Nature, History, Religion, DM Discretion)to identify the creature you are fighting and its weaknesses,  if you are able to to identify the creature your are fighting, anytime you have advantage against that creature you deal an additional damage die. In order to qualify for this, this creature cannot be a humanoid unless the humanoid creature would qualify as a monster of some kind (DM Discretion).
