Bezoar

The Bezoar is an accessory that grants the player immunity to the Poisoned debuff. It has a 1% / (1/100 / ) chance to drop from Hornets and Hardmode Moss Hornets in the Underground Jungle biome. Bezoars are also dropped from Toxic Sludges in the Underground and Cavern layers.

It is one of the ingredients required to make the Medicated Bandage, which is a crafting material required to make the Ankh Charm. The Ankh Charm can then be used to make the Ankh Shield.
