Stain Upon the Soul

Stain Upon the Soul is a mastery level 4 mystical air kiho which was named for the stigma which many of the monastic orders assign it. The kiho causes resonance between the air in the monk and their opponent, and after a successful atemi strike at their opponent it causes them excruciating pain in the nervecluster where the strike landed. Some consider it's use on oneself as an appropriate way of developing discipline. (3E p. 254)
