The Photosynthesis Potion is a craftable Hardmode buff potion. Upon consumption it grants the Photosynthesis buff, which provides 6 additional life regen when the player isn't moving. The regeneration increases to 34 during the daytime, regardless of where you are in the world. In addition, dropped hearts will heal an extra 5 HP.




  • The boosted life regeneration from the Photosynthesis buff is overridden by the effects of the Shiny Stone, the Demonshade Breastplate, the Cosmic Freeze buff, and Draedon's Heart.
  • Although the tooltip says the regeneration is 5 times stronger during the daytime, it provides up to 34 regeneration at its peak instead of the expected 30.


  • Photosynthesis is a process in which plants convert light into usable energy.
