Players can become sick when infected with diseases. Many diseases will be added, with various cure-related items, such as extracts from the Ammonite and Woolly Rhino Horn.

Disease Prevention[edit | edit source]

  • Investing attribute points in Fortitude.png Fortitude will boost your natural immunity to Disease by a small percentage. While the data isn't available, the Patch Notes for v242.6 confirm that 90 Fortitude (or 45 level-ups in Fortitude at 2 points per level-up) will grant an 80% reduction in Disease chance.
  • A Gas Mask.png Gas Mask will protect you from airborne contagions. (The gas mask will protect you from swamp fever)
