The Monster Manual describes Cambions as “the offspring of a fiend (usually a succubus or incubus) and a humanoid (usually a human). Cambions inherit aspects of both parents, but their horns, leathery wings, and sinewy tails are hallmarks of their otherworldly parentage.”
The Monster Manual describes the nothic as "a monstrous creature with terrible talons and a single great eye. When driven to violence, it uses its horrific gaze to rot the flesh from its enemies’ bones."
