Trophy Collector

You're a hunter and you enjoy collecting are pieces of you're fallen prey, whether it be skin, teeth, ears, or anything else it doesn't matter to you and long as you have a "trophy" reminding you of who or what you've hunted
You gain the following benefits:

• Much like Rangers, you have significant experience in studying, tracking, hunting, and even talking to a certain type of enemy.

  Choose a type of favored enemy: Aberrations, Beasts, Celestials, constructs, Dragons, Elementals, fey, Fiends, Giants, Monstrosities, oozes, Plants, or Undead. Alternatively, you can select two races of humanoid (such as Gnolls and orcs) as favored enemies.

• If you collect pieces of your favored enemy, you gain a bonus equal to your proficiency modifier that can you add to your attack rolls, investigation rolls, and survival rolls when you are hunting or fighting you're favorite prey.
