The Archons will not be able to control their own powers once they have been defeated. That power can be regained using their skills or magic using special item, such as the "Soul Fragments".
If the Archons were to use a magical technique, they would not be able to perform magic spells and would instead need special equipment for it to work. This way the Archons could not control their powers and the techniques would need to be learned by an adept magician. The Archons' magic equipment can be obtained through obtaining the Soul Fragments. Therefore, it is very important to learn the magic techniques of the Archons. Also, it is always a good idea to find a suitable location, such as a cemetery. By bringing your soul and then activating your "Magic Power", you will be able to revive the departed dead who have fallen to the Dark Territory. The "Soul Fragments" will help the users revive the dead so that they can fight the enemies that they encountered in the Dark Territory.
