Practitioner Term: Dream Affinite
Hidden Skill

 This skill represents an infusion of oneiric energy, the substance of
dreams, into one's essence, making one resistant to the influence of such
forces, potentially even to the point where exposure that would have been
harmful is instead restorative.  The dream affinite also can very slightly
resist the overwhelming power of divine and primal energies.  However, the
greater an affinity for dream energies one develops, the more vulnerable one
becomes to magickal, spiritual, goetic, and psionic energies.
