SwordHeart was very similar to the dome that Transcendent Martial Artists possessed; in fact, Eryke had drawn inspiration from it.
However, what made his SwordHeart unique was that he could move it according to his thoughts, unlike the immobile dome whose source was the Martial Artist.
My heart is the Sword, and the Sword is my Heart.
This saying perfectly embodied his fifth spell, the one that marked his entry into the Fifth Circle Mage. Eryke's Sword could go wherever his heart desired.
By merging his Sword Will with his Aura, he gained the ability to move his Sword with greater precision and propel it to extreme speeds in a certain area of his choice.
What was the core principle of the Sword?
It could be summed up in two words: Sharpness and Speed.
Until now, his Sword Will had focused primarily on sharpness. Although speed was present, it was never fast enough.
