Pocket Mirror

The Pocket Mirror is a Hardmode accessory that grants the player immunity to the Stoned debuff. It has a 1% / % (1/100 / ) chance of being dropped by Medusa.

Trivia

 * The Pocket Mirror is an allusion to the Greek myth of Perseus where Perseus used a shield's reflection to see Medusa so he could kill her, but is also probably a reference to Harry Potter and the Chamber of Secrets, where Hermione uses a pocket mirror to only get petrified by Slytherin's basilisk, and not killed.
 * Along with the Hand Warmer, the Pocket Mirror is one of the only two debuff-negating accessories that are not used to craft the Ankh Shield. This is likely because it was implemented after the Ankh Shield. The Ankh Shield doesn't provide any protection against the Stoned debuff, but it does protect against the Chilled debuff.
