Leech Blood is an ingredient of Lesser Antidote. It can be harvested by killing Leech, Deathworm and Lamprey. Items crafted with Leech Blood or Horns (Deathworm or Woolly Rhino): Leech Blood is a naturally obtained resource. On Aberration, Leech Blood can be collected from lampreys found in the blue zone. A Rex or Spino is recommended for this reason. 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. Using a Dino will prevent leeches from becoming attached to the player. Once finished, harvest them using the Rex or a Hatchet.
