Act 8

This ancient aggregation of machinery hails from the desert and has quirks that modern-day civilizations cannot comprehend. In battle, the Algorithm of Semi-Intransient Matrix of Overseer Network will fire its components out while its core enters an "invisible" state that hides it and increases its RES. Use Catalyze reactions to strike this core, or use Electro attacks on it during such times as the fired components have been destroyed and need to recover to cancel this invisibility and cause the core to be immobilized due to overclocking. If you fail to cancel the core's invisibility for too long, the Algorithm of Semi-Intransient Matrix of Overseer Network will begin to display its power by using a mighty overclocked attack...
