Following the same initial preparation process he used for making the "Enchantment Card: Blade of Shadows," Aiwass returned to his room and readied an unactivated Tarot card that had stored four mana points. Then he immediately went to sleep, planning to wake up early the next day to replenish his mana and make the card directly.
He was now planning to create a new "Moon" card.
Phantom cards made from the same Tarot card could only be used once in a day. The Shadow Demon was not a Superior Phantom; it was only compatible with the Moon card, whereas a Superior Phantom had multiple possibilities. This meant that if he used a new card extracted from the Shadow Demon, he would not be able to use the old "Blade of Shadows" that day.
But more and more, Aiwass felt that Blade of Shadows might not be able to handle all situations—take, for example, the time he confronted the Aberrant Limb Demon, when Blade of Shadows became completely useless.
