This is the story of a crazy lich who possesses an internal game system and brings catastrophe to the entire world. “Let’s look at the daily quests today… it’s the damned choose one-of-two-options-type again. Destroy a town with a population of 30,000 people or above; reward: 10,000 evil points. Steal lollipops from 3 children; reward: 1 evil point. If neither of the quests is completed, then 2 points will be deducted.” “Tsk! You think I’m stupid? If I really destroyed a town, a crusade of Myth-ranked Holy Knights would definitely come hunting me down. Even if I earned the points, there wouldn’t be any life left in me to spend them. I better just go be a kindly lollipop bandit.” I’ve already had enough of being a notorious lich. Who says a lich can’t be a good person? I’m definitely going to beat this damned system and be an upright and dignified good man.
So you want to fight against the undead? Most people would find either a Holy Knight or a priest of Holy Light to assist them as they were, after all, mortal enemies with the undead. Many abilities and Divine Arts of these two job classes were directly anti-undead in nature, and their specialized undead detection Divine Arts would prove very helpful.
"No undead shall ever escape the judgement of the Holy Light!" The Holy Light job class members were forever confident in this saying of theirs.
Yet, in my opinion, their ability to detect the undead wasn't as great as it seemed on the surface. It worked behind the principle of Holy Light's natural undead magic resistance. They would release a minute amount of Holy Light into their surroundings and consequently hunt for instances of resistance.
