...
To be honest.
Matthew had a conflicting mentality towards this spell.
He simply checked the description of the spell and felt that it was so evil that it even made people's hair stand on end!
Unlike the traditional spells of the world of Aindor, all the principles of spellcasting were clear, and the underlying logic was also orderly.
The spell 'Parasite's Skull' seemed to be somewhat specious.
Even Edmond.
It was also because he knew how it was, but he did not know why.
If it wasn't proven in practice, Matthew even suspected that this was a fake spell!
He composed himself.
He looked down carefully.
He found that if he wanted to practice this spell, he had to use the power of aether and his own blood to " enlighten " a specific skull.
The so-called enlightenment.
It was also a kind of ritual magic from another world.
