Blood Hawkes are usually found in swamps or marshes, but they are quite found of damp ruins and dungeons as well. Being patient hunters, the Hawkes will cling to a ceiling or vertical surface and lie in wait. Blood Hawkes are stealthy, and large targets seldom realize they have been attacked. Against humanoid targets, the Hawke's proboscis can prove quite deadly. Overall, the Blood Hawke is a weak opponent, but a successful sneak attack can spell doom for your character.
This is the fantasy version of the "aftermath" Blood Hawk found here.
