Morozova's collar from The Grisha Trilogy "If Morozova's stag can be taken, its antlers can be made into an amplifier." He reached out and tapped my collarbone— even that brief contact was enough to send a jolt of surety through me. "A necklace?" I asked, trying to picture it, still feeling the tap of his fingers at the base of my throat. He nodded. "The most powerful amplifier ever known." Solid bronze collar, to wear open slightly and close over neck to accommodate.
