A Golden Core Master and Nascent Soul Spirit Monarch uses a Magical Treasure, but when it comes to a Primordial Spirit Profound Monarch and Void Refining True Monarch, they can wield Spiritual Treasures.
Spiritual Treasures have the ability to communicate with spirits, allowing them to connect with their owner's mind, moving effortlessly with their will, possessing extraordinary mystical abilities.
Generally speaking, a Primordial Spirit Profound Monarch's Spiritual Treasure does not qualify to give birth to an Artifact Spirit. It takes until after Void Refining, when the owner's cultivation level is high, having refined the Spiritual Treasure with their heart and soul, imbued with the mystical essence of the Tao day after day, and gaining great fortune, for the possibility of it developing Spiritual Wisdom and giving birth to an Artifact Spirit.
