Act 6

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...

A Qucusaurus whose extraordinary form is a result of being unable to withstand the great power it has been granted. It will fly into the air during combat and enter the "Golden Flame" energy-gathering form, creating a shield around itself and launching a Flamewind Feather towards the ground that summons a flamewind. If you cannot destroy the Flamewind Feather before the Qucusaurus dives down into it, the creature will use a Phlogiston Current to return to the skies. This will persist until it is exhausted and returns to its original form. It seems, then, that destroying the Flamewind Feather using Elements that react with Pyro may be the key to victory...
