I decided to take that up. Just for the challenge and the enjoyment of reading Conan again. So, I went to the first Conan story The Phoenix in the Blade which can be found on the Gutenburg Project. As I remembered, there is a demon in that story. Conan fights him. I'll quote the text:
Quote:
At that instant a fearful scream burst from the rogues at the door as a black misshapen shadow fell across the wall. All but Ascalante wheeled at that cry, and then, howling like dogs, they burst blindly through the door in a raving, blaspheming mob, and scattered through the corridors in screaming flight.
Fear aura.
Quote:
The flying weapon glanced singing from the slanting skull it should have crushed, and the king was hurled half-way across the chamber by the impact of the giant body.
DR right off the bat.
Quote:
Over his mangled arm it glared fiendishly into the king's eyes, in which there began to be mirrored a likeness of the horror which stared from the dead eyes of Ascalante. Conan felt his soul shrivel and begin to be drawn out of his body, to drown in the yellow wells of cosmic horror which glimmered spectrally in the formless chaos that was growing about him and engulfing all life and sanity.
Gaze attack that sounds like save or die.
Quote:
And his outflung hand struck something his dazed fighting-brain recognized as the hilt of his broken sword. Instinctively he gripped it and struck with all the power of nerve and thew, as a man stabs with a dagger. The broken blade sank deep and Conan's arm was released as the abhorrent mouth gaped as in agony.
Magic weapons required to harm the monster. Yup, definitely DR.
So, Demons in Conan's world are incredibly strong (even Conan could not break its grip), have death gaze attacks and damage reduction. Sounds pretty close to D&D demons. Doesn't a Nabassu (sp) have pretty much exactly these abilities?
