The Medi Crystal is a one-time occurrence in the PC and Japanese versions of Tomb Raider III: Adventures of Lara Croft, where it replaces the Savegame Crystals found in the console versions of the game. It is a stationary floating green diamond-like shaped crystal. When interacted with, it replenishes Lara's health on the field in the same amount as a regular Small Medipack, and likewise, it removes the poison effect. However, Medi Crystals cannot be collected like the Save Crystals, and are instead a one-time use only.
