As the era of class awakenings dawns upon the world, Wei Xiao awakens the hidden class Necromancer.

Starting with nothing but a rusty shovel, he summons Skeleton Mages with a single gesture and endlessly expands his undead army.

Overwhelming bosses through sheer numbers, crushing everything in his path, and clearing entire battlefields alone—

When the endless sea of bones descends, all living beings are forced to kneel.

Commanding life and death, leading an army all by himself, Wei Xiao becomes a walking disaster feared by the entire world.

And from that day on, a saying spreads across the land:

Wei Xiao is the Calamity itself.
