According to the theory of five elements, Wang Mu needs balance, so he needs to wear a crystal that can grow wood or drain wood. Amethyst can enhance the properties of wood, while timely crystal can absorb wood, thus balancing the properties of beams.
In addition, you can also choose white crystals of gold and five elements or topaz of earth and five elements, but these crystals have little effect on the properties of wood.
It should be noted that in addition to crystal, you can also choose clothes or daily necessities belonging to the five elements of water to enhance the properties of water.
