There is a certain class of monster that you have dedicated your training to destroying. Choose a class of monster, which can include (but is far from limited to) beasts, constructs, demons, dragons, fae, giants, goblins, insects, oozes, plants, or undead. You gain the following:
Favour on Perception or Survival checks made to locate or track such creatures;
Add your Level to damage rolls made against the chosen creature types;
Marking a creature of the chosen type is a free action;
If the creature speaks a language, you may add one language spoken by the creature to your list of languages known.
