The foundation of Curse Witchcraft is belief; as long as a creature believes in this theory, its spirituality can attract mystical power and perform those things that completely defy common sense.
Curse Witchcraft can turn a small cat into a Giant Dragon, completely transforming both its physical qualities and its mass.
Similarly, as long as the theory permits, the small cat can also transform into a Giant Dragon.
This is also the secret behind Curse Crown being able to become the leader of the Curse School with the strength of someone who had just entered the Sixth Circle.
He created a perfect theory, almost allowing him to accomplish anything.
Of course, this "anything" is theoretical.
Any Curse Witchcraft has a success rate, which is inversely proportional to the extent that it twists reality and directly proportional to the Wizard's strength, that is, the soul strength.
