Dark Beings can found anywhere in the world. You will only be able to see them if you smoke a Vintage Cigar, Cigarette, Smoking Pipe or Cigar for 10 minutes straight.
Dark Beings will run toward you and jump toward you dealing contact damage. They also slowly drain your hunger every time they hit you. The only way to get rid of them is to eat a Dark Essence otherwise they will continuously spawn around you.
On death Dark Beings have a 10% chance to drop a Dark Essence.
