Crypt Lord

Crypt Lord (クリプトロード) is a high ranking undead that spawned from the Great Tomb of Nazarick.

Appearance
Crypt Lord dresses in a tattered purple robe which was once magnificent, and it wears a crown that shone uncharacteristically bright.

Abilities
Crypt Lord is a level 70 undead monster from Nazarick. Its commander-type skills can strengthen any Death Knights it controls. So far, it seems capable of commanding over about twenty Death Knights. However, if the Death Knights created by another summoner are controlled by a Crypt Lord, they will not gain any power buff effects whatsoever.

Trivia

 * One Crypt Lord was brought to E-Rantel to administer the security around Ainz's mansion.
