If the technique were to collide against each other, the exponential increase in power would cause terrible damage to both the opponent and the surroundings. By her own name who prohibits dishonourable fighting, Athena banned all Gold Saints from using this technique throughout all of history, whereas the technique is considered cowardly (bring three against one). Whoever dares uses this technique, will be regarded as a barbaric and dishonorable person that can never be called a Saint anymore, regardless of the intent.
