World Disaster

World Disaster is a special title and job class bestowed upon a selected few players in YGGDRASIL.

Background
In YGGDRASIL, there were actually a limited number of players who could become a World Disaster. This is because the requirement for taking levels in this class meant killing its previous holder who uses World Disaster before passing onto it's next successor.

Once a player is able to successfully obtain the World Disaster class through killings its owner, one could eventually reach the highest level of that offensive-oriented mage class to learn the supreme, ultimate spell better known as [Grand Catastrophe].

Overlord Prologue Arc
Ulbert, a holder of the World Disaster class was part of Momonga's team in conquering the Great Tomb of Nazarick. After biding his time, Ulbert is able to finally cast the Grand Catastrophe spell to eliminate five elemental spirits in an instant. At the same time, the damage output from his spell was great enough to cause the boss they were fighting to lose a considerable amount of HP.
