Felhunter

Felhunters, also known as Felstalkers and Felhounds, are a species of gruesome hound-like Demons found readily among the ranks of the Burning Legion. Felhunters are employed by every rank of the Burning Legion, and are natural consumers of magic. Felhunters possess the ability to sniff out sources of magic, arcane and demonic alike and consume upon it. A mane of wiry tentacles sprout from the wolf-like demon's back. A Felhunter uses these tentacles to latch unto it's prey and suck it dry of magic, bloating and becoming more powerful in the process.

Felhunters resemble demonic hounds somewhere at a cross between a wolf and a reptile. They possess wickedly sharp teeth, and a distinct lack of eyes. Instead, a Felhunter finds its prey completely by scent. Felhunters are the scourge of spell casters, and can hunt those gifted with magic and drain the life straight from them. Felhunters may also rapidly reproduce in this method. Spawning others of their kind from the magic they have consumed.

Interestingly, Felhunters are one of the few Demons known to defecate.
