A demonologist has spent most of their life cloistered away because of their studies. Why have they become so obsessed with demons, devils, and fiends that they would leave behind society? Do they come from a long line of warlocks and seek to know more information about the ones they’ve formed a pact with? Are they slayers of demons, devils and fiends and need to know everything about them? Are they looking to summon and control these types of beings? Or perhaps they need knowledge for a mission given to them by the church. Whatever their reasoning may be, their knowledge would surely be useful in a battle.

Skill Proficiencies: Choose two: Arcana, History, or Religion

Tool Proficiencies: None

Languages: Abyssal and Infernal

Equipment: A backpack, a set of common clothes, a hooded cloak, a silvered or cold-iron weapon you are proficient with, a bedroll, six tattered scrolls, a pouch containing 5 gp, and several (3-6) books about demons and devils (Origin of Demons and Devils, Origins of Demons, Origins of Devils, The Baatezu of Baator, The Tanar'ri of the Abyss, The Blood War, Fiend Folio, Guide to the Lower Planes, Summoning Rites and Binding Procedures, Fiendish Familiars and Their Masters, etc.)

Having spent several years of your life studying demons, devils, and fiends, you’ve gained vast knowledge about them. You are able to recognize any fiend as well as recall more than basic information about them. (i.e. resistances, vulnerabilities, special abilities, and other information the DM may choose to disclose) However, people who learn of your obsession may try to avoid contact with you if at all possible.
