The final Star Castle Mother Body will have the capability to traverse the Multidimensional Plane and conduct expedition attacks against hostile forces.
All previously constructed Star Castles in the four phases will be its fortress sub-bodies.
For instance, the lowest-level Satellite Star Castle must be entirely crafted from level 6 and above biological materials to ensure it can withstand level 6 offensives.
It must establish a comprehensive Sixth-circle array, including defenses, attacks, alerts, gathering elemental power, Void Travel, and even dimensional navigation.
It must be equipped with the Sky Dome Defense System and Demon Extermination Shuttle System, and carry at least four level 6 Mechanical Guards.
In short, all Star Castles are capable of rapidly responding to and maneuvering to defend against demon disasters.
They can pose a fatal threat to level 6 and even level 7 demons.
