Within the Necromancy System, the Death Knight is inherently a figure meant to lead armies. In terms of commanding large-scale battles, a Death Knight is far more adept than a Necromancer.
Of course, this is mainly because Necromancers prefer research over warfare, whereas Death Knights have a keener inclination towards war.
Although in terms of individual strength, there isn't much difference between a Necromancer and a Death Knight, and if a Necromancer uses all their means, it would be quite difficult for a Death Knight to defeat them.
However, on the battlefield, it must be said that a Death Knight is indeed a profession born for war.
With the arrival of Jounouchi Hiromi, the tide of the battle changed drastically.
Even though Jounouchi Hiromi is not well-versed in battle formation command, her presence as the Crimson Empress and a demigod-level Death Knight significantly boosts the combat potential of the Undead Legion.
