This was only one of its abilities. The strange energy could even affect potions, puppets, and arrays.
But another method was needed for those. They weren't like Magic Tools, which needed energy poured into them directly.
The Starry Sky College was currently using the most rudimentary method. After a millennium, they would find the method to use the Whisper Crystal's power to craft True Spirit Magic Tools and then destroy their Incarnations immediately to be replaced by something else.
The Magic Tools could be used that way, with the caveat that their strength would be weakened. But this allowed the Starry Sky College to reverse the process of the research, and they were able to craft a special Magic Tool every year.
