Dullahan

Hollows are supernatural disasters in New Erudu. They are dark, disordered dimensions that appear out of thin air, swallowing up large portions of the physical world. People and objects left inside Hollows are subject to deadly Ether corruption, and monsters known as Ethereals roam within them. Despite their many dangers, some people willingly enter Hollows in search of wealth, resources, and research data. Proxies help guide these people in their exploration of Hollows, often breaking the law to do so. Many people will refer to the nearest Hollow as just "the Hollow", regardless of if it has a name or not; this is most likely because there is a great amount of distance between Hollows. Once they have spawned, Hollows begin to create Ether-based monsters known as Ethereals. Although Ethereals have not been known to leave their Hollows, they still pose a serious threat to anyone within. During combat, Dullahan uses its longsword to charge up and perform a high-level stab, which can be interrupted by your high-level attack.
