Diabolist

Diabolist is a job class that exists in the New World.

Background
Diabolists were typically beings that are said to be evil in nature. Most of the time, Diabolists either destroyed themselves or they were slain by death squads. Though there also might be some experts in the field who had submerged themselves into the darkness, but they usually hid themselves and didn't bother to make friends.

Abilities and Powers
Among the Diabolists, very few of them were powerful in their own right.

Trivia

 * Based on the information briefly found about them in Volume 12, Diabolists are implied to be individuals capable of conjuring demons.
