Aside from being relatively likely to provoke the Primordial Demoness, the Cataclysm Scepter did not really have any major negative effects. The only troublesome thing was that its holder would gradually become attracted to it. If their will was not firm enough, they might develop an improper relationship with the scepter...
Come to think of it, I can only tell that its essence is one of Cheek's bones, but as for exactly which part of her body it came from... Forget it. I shouldn't think too deeply about that.
Having analyzed this much, Abner gave the Purple Saintess, who was under Tolzna's control, a strange glance. Then, after setting down the Cataclysm Scepter, he took out a handkerchief and wiped his hands.
Overall, two of these three items had once been carried close to Cheek's body, while the other was her "other half." All of them were closely connected to the Primordial Demoness. It was fine to use them, but they could not be destroyed for the time being, or they might "awaken" the sleeping Cheek.

In other words, you're only willing to keep the Saintess
