Hidden Skill

This skill represents the infusion of an essence of the amalgam metal into the substance of one's body, reducing the harm caused it
and things that partake of its nature, potentially even to the point where exposure becomes restorative.  One further gains the
capacity to store a reserve of amalgamal metal energy, in proportion to one's degree of affinity, should one have access to sources
of it.  However, the greater an affinity for metal one develops, the more vulnerable one becomes to the amalgam ice and related
essences.

Metal affinity can be increased by exposure to metal damage or shadow damage, as well as degraded by exposure to ice damage,
changing more quickly according to one's somatic adaptability.  If one also has ice affinity, these capabilities will slowly
degrade each other over time.

Notes

Tragically, this will not cause metal weapons to heal you - at least not at any level achievable by mere mortals (no healing from being stabbed with an iron knife on Shinichi at 250).
