Hidden Skill

This skill represents the adaptation of one's body to resist being damaged by
sharp edges, with the flesh and bone becoming harder and more ready to deflect
sharp points and resist being cut.  The higher this skill, the more resistant
one is to slashing and stabbing damage, but the more vulnerable one is to
crushing, force, and sonic damage.
