Death Knight

'I underestimated his ability to summon his undead minions.' Alex thought, looking at the Lich, who was surrounded by nearly a hundred undead of different categories and had just summoned a first-third Rank undead.

It's been ten minutes since the fight started, and even though Alex was successful in stopping the Lich from summoning a Death Knight but other than that, he hadn't done anything significant.

In the first few minutes, Alex completely dominated the Lich by spamming the darkness slash skill, chipping away almost half his Hp, but until this point, the Lich was able to summon fifty or so first Rank undead, which completely halted Alex's aggressive barrage of attacks.

After that, things just got worse and worse as the Lich kept summoning first and second Rank undead, which he used as shields against Alex to summon stronger undead.
