Plague

It was a most notorious, as well as the most feared, largescale killing magic. The spell “Plague” had made a great contribution as to why necromancers were so feared. “Plague” was a pure destructive magic. The scale of this magic was not large, but what was terrifying was that it had the ability to spread quickly. As long as one person was affected by “Plague” within a town or city, unless they were immediately burnt to death and buried, the spell would follow the person wherever they went, infecting more and more people and cause them to die as their bodies rotted. As long as a village, city, or even an empire did not quickly deal with it, the place might become a hellhole. If coupled with the spell “Corpse Reanimation”, an archmage necromancer, who was at the archmage level, would be able to reanimate all of those people who had succumbed to “Plague”, creating a terrifying zombie army out of nowhere.
