There was a reason why the Quadruple Arachnids Colony had not used poison gas balls in previous battles. That's because the poison gas ball will also kill other Quadruple Arachnids that are affected by the explosion. The Quadruple Arachnids' tactic of attacking in groups would result in more casualties for the Quadruple Arachnids Colony than for the Wilawatikta Kingdom.
But after Moku destroys the Arachnid Satellites, the functions of the Arachnids Warrior and Scout become limited by time. As a result, the sacrifice of tens of thousands of Arachnids Warriors and Scouts to kill one or two monsters is a boon for the Quadruple Arachnids Colony.
So they don't hesitate to launch poison gas ball attacks even if it means killing other Quadruple Arachnids along with their enemies.
