Necrology

Necrology was the in-depth field of study of undead creatures.

Knowledge
A necrologist could generally identify what type of undead a creature was, potentially even their weaknesses or natural defenses. They were also knowledgeable in the history of different undead, their dining habits, and where they were likely to lair.

Education
The Chanty of St. Sammaster, a temple run by the Cult of the Dragon, had a library that contained many books and scrolls on the topic of necrology.
