Gameplay evidence
Story encounter
At roughly 10:33–11:44 in the supplied developer gameplay, the group is described as looking for Supreme Evoker before Copper Monstrosity appears as the major story encounter.
What happens after the fight?
At roughly 12:00–12:40 the group picks up a Note Block. The developers state that this object is important to the story, while deliberately withholding the full explanation.
Attacks and strategy
The transcript proves the boss name and story context, but it is not enough to write a reliable phase/attack guide. Those fields remain open until the actual fight footage is reviewed frame by frame.
