Leech Blood is a naturally obtained resource. It can be harvested by killing  Leech,  Deathworm and  Lamprey.

Leech Blood is an ingredient of  Lesser Antidote.

The easiest way to collect Leech Blood is to build a Wooden Raft with a room and an open deck, and sail to the swamps.

  • Use a crossbow (or other ranged weapon if necessary) while on the raft deck to kill the leeches without risking them attaching to you then harvest the leech blood using a  Metal Hatchet.
  • If a  Titanoboa gets near, hide in the room and use a melee weapon to kill it when it clips inside the room.
  • Have a campfire going inside the raft room in order to burn off any leeches that latch on during harvest or to cook up prime meat from the  Titanoboa.
  • If you don't build the boat out of stone, beware of  Sarcos since they can do decent damage to wooden structures.

Another option is to ride a Rex into the swamps and kill all the leeches. Once finished, harvest them using the Rex or a Hatchet. Using a Dino will prevent leeches from becoming attached to the player. This method will work with any carnivore but to be safe from Kaprosuchus' grab ability make sure your Dino is immune to it, usually by being too big to carry. A Rex or Spino is recommended for this reason.

On Aberration, Leech Blood can be collected from lampreys found in the blue zone.
