Orb wraiths were incorporeal undead formed when half a dozen or more wraiths merged together at a location of powerful negative energy.
Appearing somewhat like an enormous mass of darkness comprised of various humanoid features, an orb wraith was a constantly shifting amalgam of insubstantial limbs, faces, and shining red eyes. Numerous bolts of purple-black negative energy would crackle and spark throughout an orb wraith's body, not unlike a thundercloud.
Although an orb wraith lacked the physical presence to exert force upon its surroundings, the creature was notably swift and able to react quickly to multiple enemies, despite its size.
As essentially a conglomeration of ordinary wraiths, an orb wraith shared much of their twisted mentality. However, an orb wraith seemed to also manifest a much higher intellect than its lesser kin.
Orb wraiths rarely appeared outside of the Negative Energy Plane, but on the few occasions they did it was only within concentrated areas of negative energy, hence earning their "orb" moniker.
