What is the role of the 12 constellation fragment in the riddle of the flame coat of arms?

Not alone. After collecting all 12 pieces, it will become a pearl of stars, and then the seal of Emperor Harding will be combined with other beads to form a seal shield (flame coat). At the end of this chapter, there is a plot in which a demon Ganev becomes Mars and his sister Alice cheats everyone. If all the pieces are collected to complete the shield, the plot will be seen through, and the game will continue to complete the real ending of defeating Medea, otherwise it will end directly, commonly known as the false ending. The role of the Pearl of the Star is to carry all abilities plus 2 and the number of weapons used will not decrease. The shield disappeared after it was synthesized. Shields are rubbish, and their function is only to add 2 to all abilities. Just open the treasure chest (it should be) at will, and there is no way out. If you want to finish the real ending, you can only sacrifice all the beads, otherwise the chapter will be turned out and all the important props will be posted at last.
