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 without being petrified.
 * Prior to 1.4.4, the Pocket Mirror was 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.
