The Stone Assimilator is a machine added by Calculator. It is used to automatically extract Hunger Points and Health Points from Amethyst Trees and Tanzanite Trees respectively.
Placing it next to an Amethyst or Tanzanite Tree, facing the tree, will cause it to periodically harvest their leaves for Hunger or Health Points. Those can then be extracted by putting a Hunger Module, Health Module or Nutrition Module inside the Assimilator's GUI.
