Although Lux's subordinates had now learned the Death God's Aura [EX] Skill, they still needed to put it into practice.
Lux thought that by simply activating the skill, he would be able to use its benefits. But, to his surprise, the skill was not as simple as he thought it would be.
Hereswith explained that the Death God's Aura wasn't a passive skill but an active skill. She had created this skill in order to combine the power of light and darkness, which she managed to do after years of painstaking trial and error.
In order to use it well, one had to master the feeling of being one with this ability. When Lux first tried using it, the skill only lasted for half a minute before dispersing completely.
