As it is said, besides suppressing the Primordial Chaos and executing the function of creation within itself—of course, if performing the act of creation inside the Chaos Pearl could even be considered a function—it possessed yet another capability: placing Spirit Treasures into the Chaos Pearl allowed those Spirit Treasures to upgrade.
