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.

Abilities and Powers
When comparing this class to the other magical job classes, World Disaster is said to be the strongest in terms of pure firepower. World Disaster was a class which mainly specialized in destructive magic. It was a type of class built with incredible firepower on the offensive side of battle. However, the MP consumption rate for using the spells offered in this class is quite high. The class's horrible mana pool was consider not suited for long-term adventures alone without a party. Still, their terrific firepower is not comparable to carpet bombing.

Because World Disaster is so specialized, solo-play becomes nearly impossible at higher level areas or dungeons. The passive skill that increases magic power damage is a curse, so one cannot deactivate it. Most people who are lucky enough to have the World Disaster class greatly used wands, scrolls, or staves. For that reason, World Disaster has a complicated but niche popularity. According to Maruyama, it was the kind of class that someone wants in the party but doesn’t want to play themselves while facing powerful monsters.

In the Web Novel, it was described to be a class which focuses on attack.

Trivia
