On the skin scroll documenting soul arts, Frode once read a record, clearly noting that aside from following conventional steps, there's another method to learn soul arts:
Through killing and absorbing the special energy of the undead, to assist in practicing soul arts.
This method actually has many limitations and might lead to self-degradation due to the chaotic energy within the undead.
Moreover, the soul arts acquired from absorbing undead must be consistent with the abilities that the undead themselves possessed.
For example, if an undead only knows the 'possession' ability, then through this special method, the first soul art learned can only be possession.
Most importantly, the effectiveness of the absorbed soul arts may be uncertain, making self-cultivation preferable for more choices and to avoid degeneration.
Previously, Frode never considered using this method.
However, now he has heard about the Spider Undead Lady Cilla.
