Reverted Undead?

Like dropping a pebble into a pond, the attack disrupted the air in the area and caused everything to go blurry.

When the half-undead saw the fan-shaped ripple covering all possible escape routes, he stumbled back in fear as he felt the deadly energy. While trembling in a corner, he begged for his life.

From Angor's previous experience, undead souls would dive into the attack without a second thought since they could neither think nor did they know what "fear" was.

It seemed his white bullet did more than arousing intelligence.

No one would believe him if he ever said that an undead actually tried to escape from danger. One reason why wizards would like to avoid anything related to undead creatures was that these things were fearless and extremely difficult to wipe out. For anything that knew to back off from danger, wizards simply had to exert their pressure to get rid of them.
