Classical "bone changing" (huan gu). The skeletal frame is said to alter in density.

This entry is a reconstruction. The Mo Pai sources do not publish a curriculum for level 28, so what appears above is drawn from classical Taoist internal alchemy and from the shape the Mo Pai literature implies for the "Purification of the Vessel" band. It is a map of the territory the tradition describes, written by this archive rather than taken from the lineage.

Signs and effects

The skeletal frame is said to alter in density.
