A piercing sword aura managed to damage the throat of the Primordial Beast of Greed. The pain of having one's throat get pierced and internally bleed made the Primordial Beast of Greed thrash about. All of the golden army members also momentarily lost their control as each of their movement is somewhat connected to the Primordial Beast of Greed.
The golden army might have the ability to do the commands of the ones that summoned it, but it is also a weakness as well. The golden army is still connected to the summoner and could be interfered with as seen as what is happening now. The Primordial Beast of Greed might not have intended for the golden army to even show any unusual behavior but the pain it felt has overshadowed its control.
