In the story mode, attack and defense are mostly effective, but in some levels, such as some levels in the Red Magic Tower, attack and defense are not effective. In this mode, even if the attack is only doubled, it will be judged as ineffective. If it hits the opponent's person or object, it will only make them dizzy without causing any damage. This restriction will only be lifted after several rounds, at least three to four rounds, to achieve a one hit kill effect. However, during this process, the opponent's character has already been killed, because in this mode, the defense multiplier is also ineffective, and the damage caused by the opponent's attack is normal, which often leads to serious blockages. May I ask what the reason for this malfunction is, and is there a solution? I hope a big fish can clarify this.
