They hang from the ceiling by four small tendrils, and they cling to most anything and then spread out their sail perpendicular to the walls. The sturdy sail is about eight inches wide and about six inches tall. Boney spines lace the length of the sail at regular intervals, strengthening it. The sail itself is bright blue or green, translucent, and covered in small eyelike dark spots. \n'b'  Hunters in the Dark . Aothsil cling to the ceilings of dungeons, old corridors, or anywhere that darkness prevails. They hang dormant until some passing creature disturbs the air. They nest in pods of two or three dozen, spread out over a large area, sometimes hundreds of feet apart. They are mindless, reacting on instincts only. When anything comes within 100 feet of the aothsil, it opens the sail very slowly, ensuring that anything watching it does not notice the movement. When the creature moves to within 20 feet of the aothsil, it detaches from the ceiling, gliding through the air via its sail. Its pod opens on the top and a small tongue-like appendage snakes out. When it passes within a few inches of its victim, the tongue strikes the creature, delivering an electrical shock and attaches to the victim. Once secured to a victim, it stabs it with its stinger.'
