Sky Leeches are airborne insects in Avatar: Frontiers of Pandora living at high altitudes, near unique natural structures like floating rocks and cliffs, where they form colonies. They have streamlined, muscular bodies for quick aerial maneuvers and brightly coloured, fast-moving wings to swiftly pursue targets. In defence or while hunting, they attack in groups, using three hooked claws to sting and cut their prey. After weakening their target, they attach themselves to it and use their underbody mouth to draw blood.[1]
Flying through a swarm of Sky Leeches will cause a barely noticeable amount of damage to your health.
