Global: Why Are Your Undead So Weird?

(Pseudo-DnD, more like a mash-up. I hope you enjoy it.)

The Abyss's invasion awakened the world's will, ushering in an era where everyone could become extraordinary. The Abyss watched hungrily, and the evil gods drooled in anticipation!

The course of the world's development was changed completely. Every young man and woman who turned eighteen would undergo a class awakening.

Powerful class holders were symbols of status and position, and the only ones who could defend against invasions from the Abyss and evil gods.

You could be as insignificant as a blade of grass, serving as cannon fodder on the front line where the world clashed with the Abyss, or live out a simple, ordinary life in the peaceful rear. Of course, you could also choose to swim against the current, becoming a revered legend and an epic celebrated by all!

On the day of his awakening, Chen Chen gained the hidden main class of Necromancer, but his secondary class, Teacher, seemed completely incompatible with it. Little did he know that this secondary class was far more than it appeared. A legendary secondary class would give the undead limitless possibilities.

Have you ever seen a skeleton unleash a sword aura? A lich cast Meteor Shower? A vampire cast healing spells and resurrect fallen allies? Or terrifying Guardian Knights, Dark Berserkers, Monk Abominations, and Wraith Assassins?

It all began when a Necromancer acquired the secondary class of Teacher.
