Secret Spirit Skill is a skill for Symbol Master as it needs Mental Energy. It is split into various levels which represented and was named by the three most important aspects that made up a human. From low to high, Essence, Qi, Soul. Prior to the Essence Level, there was still a normal level. The Secret Spirit Skills of most Symbol Masters were at this level. Although the Materialized Spirit Needle that Grand Master Gu used that day sounded rather domineering, it was only a normal Secret Spirit Skill. To obtain a strong Secret Spirit Skill was not such an easy feat.
