  At Level 3: 
  You gain proficiency in Medicine and Nature. 
  You gain proficiency in all Martial Weapons. 
  You gain proficiency in Leatherworker’s tools and gain a set of Leatherworker’s tools. 
  Practiced Inspection: As a bonus action when you make a melee attack against a creature (regardless of 
  whether or not you hit), you can examine your enemy's reaction to your attack.  You learn either: the enemy's AC or 
  you learn if that enemy had resistance to any of the damage of that attack (also learning which of those damages it 
  had resistance to, and learning about vulnerabilities from that same attack in the same manner, you cannot learn 
  resistances or vulnerabilities unless the attack hits).  In addition, you can spend 1 hour dissecting a creature's corpse, 
  make a medicine check with a DC equal to the creature's challenge rating.  If you fail the corpse is rendered 
  unusable and a second check cannot be made (this also applies to Monster Extracts).  If you succeed, you learn all 
  resistances, immunities and vulnerabilities it has.  You also learn its Size, Armor Class, abilities, what types of 
  attacks it can make, and if it has legendary resistances or actions.  (You do not learn what spells a creature can cast, 
  only whether or not it can cast them.  Likewise, you do not learn what number of legendary resistances and actions 
  just that they exist.  You learn what the name of the attack is but do not learn any bonuses or dice rolls.)  A creature 
  dissected in this way cannot be raised from the dead using their body, this does not apply to constructs.  If using this 
  feature to disassemble a construct you also learn all ability scores of that construct.  
  Monster Enchiridion: During a rest, you record all information that you found on creatures in a book that 
  you carry with you, recording it for future use and posterity.  
  Monster Extracts: You can spend 1 hour dissecting the corpse of a monstrosity, aberration, beast, or fey to 
  extract one of its abilities.  Make a medicine check with a DC equal to twice the creature's challenge rating and if 
  you succeed, choose one ability, sense, or movement speed (other than flying).  You gain an Extract with the same 
  name as the ability, sense, or movement speed (You cannot gain legendary resistances, legendary actions or 
  spellcasting abilities from this).  If you fail the check the corpse is rendered unusable and a second check cannot be 
  made (this also applies to Practiced Inspection).  A creature dissected in this way cannot be raised from the dead 
  using their body.  You cannot gain any extract from a construct. 
  Extract Integration:  During a long rest, you can use your magic to modify yourself temporarily to gain the 
  ability of that Extract, making that Extract active.  You can also change an active Extract for another during a long 
  rest.  You can have only one Extract active at a time.  This increases to a maximum of 2 at 6th level and 3 at 14th 
  level. 
   
  At level 6: When you dissect a creature using your practiced inspection feature, you also learn the Strength, 
  Dexterity, and Constitution scores of that creature.  In addition, you may now switch active Extracts during a short 
  rest as well as a long rest. 
  
   
  At level 14: 
  Mastery of Knowledge: You have memorized and mastered the knowledge that you gained during 
  dissection.  When in combat, if you hit with an attack against a foe that you have dissected using the Practiced 
  Inspection feature, you can use a bonus action to bypass their natural defenses.  If that creature has resistance to any 
  of the damage types included in the attack, it loses it in regard to that attack.
