Hidden Skill

This skill represents the conditioning of one's body to resist being damaged by the amalgam void and essences that partake of its
nature.

Void resistance can be increased by exposure to void damage, changing more quickly according to one's somatic adaptability.  It
will decay over time, weakening more quickly according to one's somatic adaptability.
