Only the most proper education in magic possible would produce a clingy bastard of such caliber!
This Lich and Ujfalusi were both level-20 Necromancers, and were both able to summon a Humerus Wyrm, yet they were worlds apart in terms of combat skills. While Ujfalusi had once ruled over the ruins of Syer Town, he was nothing more than a harmless lamb compared to this clingy bastard—there was no way to compare them at all.
This bastard was awfully difficult to deal with because while he was skilled in Necromagic, he did not use any summoning spells, which were the most effective spells Necromagic had to offer. Even though he conjured hundreds of corpses using death aura, they were only meant for the last Corpse Explosion.
There was only one reason why a Necromancer did not summon Undead creatures—it meant that he had far more powerful tricks up his sleeve.
