Carrion is a dangerous, possibly unique, fiend from the hellish planes. It pretends that the knight atop it is the source of its intelligence, but in truth, the knight is a decoy, diverting attacks from the devil's actual body. When too severely damaged, it drops the knight's body and flees, like a lizard losing a tail. It climbs like a spider, and can strike with that flaming sword or fling flame from it. It also claws and bites.
