Anechoic Plating

Anechoic Plating is a pre-hardmode accessory found in Shadow Chests in the Abyss. It reduces Abyss creatures' ability to detect you there, and also reduces the defense reduction from the Abyss to one third.

Trivia

 * In real life, anechoic plating is used to make rooms that completely block out sound.
