The Philosopher's Stone is a Hardmode accessory which decreases the Potion Sickness debuff duration by 25%. Therefore, 45 seconds after consuming a recovery potion while the Philosopher's Stone is equipped, another one can be consumed. It has a (Desktop, Console, Mobile and 3DS versions) 1/6 (16.67%) / (Old-gen console version) 1/7 (14.29%) chance to be dropped by Mimics.

  • (Desktop, Console and Mobile versions) The reduction on the duration of Potion Sickness debuff is dynamically updated, meaning that equipping the Philosopher's Stone will proportionally decrease the duration of Potion Sickness, while unequipping it will proportionally increase the duration.
  • (Old-gen console and 3DS versions) The reduction on the duration of Potion Sickness debuff is determined when the potion is consumed. If the Philosopher's Stone is equipped when the potion is consumed, then the duration will be decreased by 25%, and unequipping it afterwards has no impact on the remaining duration.
  • (Desktop, Console and Mobile versions) The reduction effect works on the Restoration Potion's cooldown of 45 seconds as well, decreasing it to 33.75 seconds.
  • The Philosopher's Stone's duration reduction effect does not stack with Charm of Myths'.


  • (Old-gen console and 3DS versions) Because the effect only applies the instant a recovery potion is consumed, it may be preferable to keep the Philosopher's Stone in a vanity slot and only swap to it when consuming a recovery potion.


  • The philosopher's stone is a legendary alchemical substance capable of transmuting base metals such as mercury into gold or silver. It is also called the elixir of life, useful for rejuvenation and for achieving immortality. According to alchemical texts, the philosopher's stone came in two varieties: white (for the purpose of making silver), and red (for the purpose of making gold), the white stone being a less matured version of the red stone. Sometimes, the color of the stone's solid form is described as an intermediate between red and purple, transparent and glass-like. While the Philosopher's Stone of Terraria does not convert metals, it is related to rejuvenation, as it allows to heal more often. Furthermore, its appearance is consistent with the alchemical descriptions.


  • Desktop 1.4.4: Potion Sickness reduction is no longer "front-loaded" at the time of using the potion. Instead, the cooldown is dynamically updated whenever the accessory is equipped. Equipping it will reduce the remaining cooldown proportionally, and removing it will increase the remaining cooldown proportionally.
