Blindfold

The Blindfold is a Hardmode accessory that has a 1% / (1/100 / ) chance to drop from Corrupt Slimes, Slimelings, Shadow Slimes, Crimslimes , Dark Mummies, and Blood Mummies. This item grants immunity for the equipped player to the Darkness debuff; however, it will not protect the player from Blackout or Obstructed, nor cancel out the positive effects of Shine or Night Owl.

It is one of the ingredients required to make the Ankh Charm, which is in turn required to make the Ankh Shield.

Trivia

 * The Blindfold is the only accessory used in the Ankh Charm crafting recipe that is not itself involved in or crafted by any other recipe.
 * The Blindfold is the only Ankh Charm material that is visible when equipped.
 * A real-life usually disables the wearer's sight instead of preventing sight-deteriorating effects.
 * However it is known for fictional characters to wear blindfolds to reduce their dependency on vision, and thereby heighten their other senses.
 * In Terraria, the character may be using the blindfold to "see without their eyes," which would negate any visual impairment.
