Cursed Knight

Cursed Knight is a job class that hailed originally from YGGDRASIL.

Background
In YGGDRASIL, Cursed Knights were designed to have the backstory of being corrupted cleric-knights who had been cursed, and they were considered to be a very strong job class. However, this class had a lot of drawbacks, so they were not very popular among players to invest levels in.

The prerequisites to become a Cursed Knight is that the person must at least be level 60 or higher.

Known Cursed Knights

 * Shalltear Bloodfallen
 * Leinas Rockbruise
 * Black Knight

Abilities and Powers
Among the skills Cursed Knights could possibly learn, there are ones which gave them the ability to release waves of darkness, inflict cursed wounds which could not be healed by low-level healing spells, instant death curses, and so on. According to Ainz himself, to have learned all of these skills meant that the Cursed Knight has to be level 70 at a minimum.

Passive

 * Destruction of Low Level Item: In the Web Novel, Cursed Knights have the natural ability to damage magic items that are level 40 or lower if they equipped one.

Trivia

 * In the New World, there exists a legendary set of weapons famously known as the Four Swords of Darkness once owned by the Black Knight of the Thirteen Heroes which had powers comparable to that of the Cursed Knight class.
 * In Mass for the Dead, Shalltear Bloodfallen creates the adventurer identity of "Shall" who is a Cleric sealed by a curse. Though she has the option of using her backstory as a Cursed Knight, she believed using the former was appropriate as the latter job class was noted to be a very high level, something that would raise eyes for such a girl like her in the New World.
 * In Leinas Rockbruise’s case, while some job classes from YGGDRASIL require prerequisites, natives of the New World are still able to learn professions without the need for prerequisites.
