Berbalang

Berbalang, was an evil creature from the Astral Plane. It remained there in a comatose state. When it ventured to the Prime Material plane, it was to feed on humans.

Description
The Berbalang was a biped, gaunt and lanky. It had leathery skin, which was black in color. It had wide eyes, which glowed and were white. Their eyes had Infravision abilities. They had a pair of broad, bat-like wings on their back. These allowed the Berbalang to be able to fly, and could do so with speed and agility. It has very sharp claws and needle-like teeth.

Combat
The Berbalang used its ability to fly to give it an advantage during combat. It used it claws and teeth as weapons. Its projection was immune to charm, hold and sleep spells. The projection would attempt to flee combat if it is struck. If the projection was killed, it was likely the physical body would also be slain.

Ecology
Most of its life was spent in a coma, with its spirit wandering the Astral Plane. Its spirit would stalk other astral creatures. The Belabra had a complex ritual for courtship and mating. It's only food was freshly killed human flesh. It returned to the Prime Material plain to feed, once a month on the full moon, usually for three days. It would find a suitable lair and then would manifest an exact duplicate of itself, a projection. This projection could roam up to three miles from the Berbalangs physical body.

If the projection killed a human, it would bring the corpse to the physical Berbalang, the projection feeding off the body while in flight. The Berbalang's hunger was usually satisfied by the time the projection returns with the body.

The Berbalang choose a new lair every three to four months to avoid detection.
