Rare objects or creatures that magnify a Grisha's power. When a Grisha bonds with an amplifier - typically made from the bones or scales of certain rare animals - their abilities are dramatically enhanced. Each Grisha can bond with only one amplifier (a rule the Darkling seeks to circumvent). The most powerful amplifiers are Morozova's three legendary creations: the Stag, the Sea Whip, and the Firebird, which are said to grant their bearer near-limitless power when combined.
