A land lamprey drains blood, dealing 1d4 points of Constitution damage in any round when it begins its turn attached to a victim. 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.
