This feature grants you the Research Creatures ability as detailed in the Researching Creatures in Apendix A. You may only use this ability to research creatures with the Monstrosity, Abberation, or Giant type, and you may use an Investigation, Animal Handling, or Survival check to complete your ability. You may reduce the time it takes to research a creature to 30 min if able to physically examine or watch the creature or species in question. Additionally, you may lower the DC of your research check by 2 for every additional feature you take from the Research Weakness Feature Tree: Research Weakness: Beasts and Plants, Research Weakness: Monsters, Research Weakness: Disease and the Undead, Research Weakness: Humans and Androids, Research Weakness: Aliens.
