Under normal conditions, the soul energy within these crystals could not be directly absorbed, or else one would be eroded by the mixed Void Energy. Therefore, they were used by the Ancient Civilization of different races as the driving core of these war puppets.

However, as years beyond count passed, these Soul Crystals within the stone statues continuously purified, turning into pure soul crystals, which could strengthen the soul to a certain extent upon absorption.
