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.


Used in[]


  • This item can also be obtained from the Abyssal Crate after the Skeletron has been defeated.
  • When used in tandem with the Fathom Swarmer Breastplate, defense loss in the Abyss is reduced by 80%, rather than 73.6% that would naturally arise from equipping both.


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