Dybbuk (Dungeons & Dragons)

context
In the "Dungeons & Dragons" fantasy role-playing game, the dybbuk is a type of demon.

Dybbuks belong to the race of demon called loumara. Dybbuks are incorporeal creatures and so they do not have a specific physical form. Their shape resembles a jellyfish with a simply sketched human face.

Dybbuks can possess and control dead bodies, so they spent a lot of time looking for a good body to animate. After taking the control of a body, dybbuks try to insert themselves in the society of the victim, pursuing their plans or, more probably, looking for a better body.

Dybbuks are lonely creatures and they can be found in group only where they can find a lot of corpse to possess, such as on a battlefield.
