Sin and Virtue Curses

Magic/mana has two forms: Abstract Magic and Corporeal Magic. Abstract Magic Attributes can't cause physical harm, opposite to the Corporeal Magic Attributes.

Attributes like water, earth, lighting, wind, and such elements were all corporeal magic. While attributes such as holy, dark, shadow, curses, and such elements fall under the category of Abstract Magic. 

The Abstract Magic could directly cause harm to the mind, and it was physically harmless. This type of magic was very hard to master and complex in many ways. The owners of such magic can't use their mana to strengthen their weapons or use them in physical combat. But if someone mastered Abstract Magic, it was very hard to guard against their attacks.

The Curse Abstract Magic was as mysterious as the Holy Abstract Magic, and these two attributes were the bane of each other. Furthermore, the scoop of these two abstract attributes was so vast that they were divided into many branches.
