This Nether Water Herb can be used to break through above Purple Crystal Soul Master and even strengthen their soul to a certain degree. If the Soul Master's Soul Mark is water-attributed, a Soul Master could awaken another Origin Skill.
A Soul Master like Emrys who doesn't have a water-attributed Soul Mark, he can refine the Nether Water Herb and obtain one or two drops of Nether Water which can revitalize the body and soul, heal wounds, and restore consumed energy. Moreover, Nether Water can temporarily enhance a Soul Master's power level temporary as well.
But it also has side effects. It may cause a Soul Cultivator's soul to be tainted with dark energies, transforming him or her into a Soul Demon from Soul Master. Of course, something like this is very rare to occur.
