The opponent's Inner Strength is much higher than his, and the spells mastered are extremely well-hidden secret techniques. He was restrained even before detecting a certain loophole. Such spells are very rare; the more a spell is used, the more likely it is to be exposed, known by more people, and the countermeasures will be included in more "recommended patch packs." The more people hold the countermeasure patches, the lower the probability that this spell will be effective next time.
