The King of The Dead
This was Triple X's class and also the title he was given to by the Underworld after the numerous battles he had fought in the Amphitheatre.
The main ability of his class was to turn a corpse into an undead, and the higher the quantity of his mana, the more corpses he could resurrect, turn into undead, and store in a separate space that was attached to him.
In a battlefield involving thousands of corpses or more, Triple X was a one man army that could strike fear and terror into the hearts of many armies.
Divine knew this, and he also knew of the immense potential Triple X had because of his class.
The word, 'King', in his class was not taken with levity because from what he knew, any class with the word, King, had the potential to make one reach Tier 8. A Tier which was immense in their Universe.
One of the reasons why Divine had been so worried about Corey was because their environment was one that favoured Triple X heavily.
