Even though he had concentrated most of his efforts in those days toward training on the poison techniques, Yang Ling did not neglect his other Wizard Techniques.
He only truly came into contact with Wizard Techniques that allowed him to control souls after having advanced to the level of Heaven Wizard. There were several other Wizard Mantras for various miraculous abilities. One of those was the mysterious Gaze of Confusion Wizard Mantra.
According to the explanation on the stele, the Gaze of Confusion was an illusory Wizard Technique that covered a broad area. Its power was dependent on the strength of the caster's mental energy.
At a low level, he could use his mental energy to confuse his opponent's senses of sight, hearing and smell. He could target an attack toward an individual, or let it loose in a more blanketed attack. After training the technique to a high level, he could confuse the thoughts of his enemies, causing them to descend into confusion.
