This is used to give/get blood from other animals or monsters in the world. Injecting a plasmid into an entity's blood will cause the entity to get the traits of that gene. (Not all genes that work on the player will work on other mobs!)

Left click to take blood from an animal, shift left click to give blood back. It must be given to the same type of mob it was taken from.
