Starfinder: Glowing Thirst
War – war never changes. Technology, when combined with necromatic arts can and has produced monsters as horrible as anything seen in the distant past.
The overall appearance of this particular breed of vampire is that of a grey-skinned, hairless human with white eyes, pointed elf-like ears, bat-like wings and fangs. They also appear to be malnourished, as the flesh of these creatures is pulled tightly over their musculature, making them look sickly and oddly enough – powerful at the same time. What gives these vampire’s the name is the bright-green glow they give off, which makes it difficult to say the least for them to try and sneak up on other creatures.
Like many of the varying types of vampires, these undead monsters are susceptible to ultraviolet radiation, which will kill them in a matter of less than a minute if they are exposed to such.
These creatures are mindless. They have no intelligence and live strictly to feed and sleep. They always sleep during the daylight hours, well hidden from the sun and would-be hunters. Like bats, they hang from the roof or ceiling of their homes.
When forced to fight on the ground, the creatures are capable of clawing and biting. They can only bite while flying, as their wings are too busy keeping them aloft to do anything else. The bite will also inject a paralytic poison which they use to try and ensure any prey will be more docile when it comes to feeding.
Strangely enough, these beasts will only feed for a maximum of six rounds, draining 1d6+1 points of blood damage per round, up to a maximum of 18 hit points. If the victim expires before this, they will target a new source for blood and pick up where they left off, so if a victim died after four rounds of blood drain, they will only feed for two rounds off the next victim before making their escape.
No matter what, once they have sated their hunger, they will leave the creature. This does not mean that another might come and take its place, but more than a few victims have survived their encounter with these creatures as a result.
