Blood Drain. Once the stygian mosquito successfully hits a target, it remains attached and starts sucking blood. The target loses 1 point of constitution per round. Each stygian mosquito sucks a maximum of 4 points of constitution and then withdraws.
COMBAT & TACTICS
Stygian mosquitos are beta predators in their ecosystem, feeding on wounded or solitary creatures. However, their true strength manifests when they attack in a swarm. A swarm of stygian mosquitos can easily kill larger prey, even alpha predators, provided their stinger can pierce through the skin.
DESCRIPTION
Stygian mosquitos are oversized mosquito-like creatures. Their size range from 10 centimeters, with some species growing up to 1 meter in length. They usually have spongy and light body and their colors vary from a dull grey to a pale brown. They fly employing a couple, sometimes more, strong bat-like wings
and the head mounts a sharp stinger.
HABITAT
Stygian mosquitoes have proven to be very versatile in terms of adaptability, even if it is very rare to encounter these creatures in an extreme environment. High-pressure atmospheres and planets with moderate winds are their favorite terrains. They are extremely resilient and can remain at high altitudes for days if required. They nest inside caves located in rocky formations, preferring narrow tunnels and
subterranean caves.
BIOLOGY
The biology of stygian mosquitos does not differ too much from that of an insect. This kind of life form easily evolves on planets suitable to host life at its early stage. They feed on the blood of carbon-based life forms, which are the only ones that can provide edible blood – or humors in general – for their metabolism.
