Once it has dealt 4 points of Constitution damage, it detaches and slithers off to digest the meal. If its victim dies before the land lamprey’s appetite has been sated, the land lamprey detaches and seeks a new target.
Environment temperate plains and forests and underground
Organization solitary, pack (2-5), or swarm (6-11)
Land lampreys can be found in all but the hottest and the coldest environments. They prefer the dark and dampness of the subterranean world and so are most often encountered there.
A land lamprey attacks by attaching to a victim and draining blood. An application of fire causes the land lamprey to releases its hold and move away from the source of the flame.
