Hidden Skill

This skill represents the infusion of an essence of the amalgam lightning into
the substance of one's body, reducing the harm caused by such forces, potentially
even to the point where exposure becomes restorative.  This is also true, to a lesser
extent, of extropy, elemental air, and the amalgams heat, thunder, light, steam,
smoke, mist, and shadow.  One further gains the capacity to store a reserve of amalgamal
lightning energy, in proportion to one's degree of affinity, should one have access to
sources of it.  However, the greater an affinity for lightning one develops, the more
vulnerable one becomes to the amalgam void, and to a lesser degree entropy, elemental
earth, and the amalgams cold, ice, darkness, salt, mud, magma, and eskara.
