Amulet of Affinity

This shard of amethyst is psionically honed to be a perfect repository for energy. It is comprised of a lattice of particles which, when inert, are sensitive to metaphysical forces. When placed in a metaphysical energy field, the crystals align to that field; thereafter, it is possible to direct pure energy through the crystal, and form that energy into an exact duplicate of the original effect. This action resets the crystals to a neutral position.
