Old School Monsters: Displacer Beast

At the risk of attracting the Hentacle and cosplay crowd, i'm going to post about the tentacled Displacer Beast (apparently the pet of the Dirty Pair), a criminally underutilized Dungeons and Dragons villain.

The Displacer Beast is no ordinary old-school monster. Simply describing the Displacer Beast as a monster fails to do justice to the Displacer Beast's potential.

The Displacer Beast is a fascinating addition to the DnD universe, appearing very early in the bestiaries of the Dungeons and Dragons role playing game. The Displacer Beast dates back to the 1975 Greyhawk D&D supplement and is based on an antagonist created by A. Elton van Vogt in 1939. That creature is the Coeurl, and appears in the story "Black Destroyer". It, along with the Ixtl from van Vogt's "Discord In Scarlet", provided inspiration for the Aliens Movie cycle.

In Dungeons and Dragons, the Displacer Beast is described as a black, six-legged, puma-like creature, with at least two tentacles sprouting from its back. The original 1977 AD&D Monster Manual does not tell us how big it is. However, it has six hit dice, suggesting that it is fairly large.
In the DnD mythology, the Displacer Beast and the Blink Dog are described as mortal enemies, not surprising since Displacer Beasts are evil and Blink Dogs, good. Pictured above is a pack of Blink Dogs, chowing down on a dead Displacer Beast. This looks to be a David Trampier piece, but someone can correct me on that score. The bottom illustration from the 1977 Monster Manual is definitely Trampier.

The image below is from Tony DiTerlizzi's blog. He was the illustrator for the 1994 Monstrous Manual Displacer Beast. In the Monstrous Manual, we discover that the Displacer Beast is eight to 12 feet long. It's notable ability is that it appears to be "displaced" several feet from its actual position. A rather banal ability, which simply makes it more difficult to hit in combat. Yawn.

I say that the Displacer Beast is an underutilized villain, because the creature on which it is based makes for an interesting denizen within the first three levels of a dungeon. To give you a sense of its potential, I give you a passage from a review of Voyage of the Space Beagle, from The Quill & The Keyboard:

"Coeurl (the Displacer Beast) tries to pass himself off to the Earthmen as an animal worthy of study, but his insatiable hunger, criminal nature, and contempt for the primitive visitors exposes him to suspicion after he murders one of the crew. Soon it is a battle of wits as Coeurl keeps the Earthmen guessing while the explorers try to determine the alien's guilt and the extent of its incredible powers."

Not all dungeon denizens are meant to be fought, at least not initially. In the case of the Displacer Beast, this creature is better utilized as a source of adventure hooks.

In Voyage of the Space Beagle, the Coeurl needs to feed off the id of its' prey. What if the id is analogous to hit dice, and the Displacer Beast gets more bang-for-the-buck from those with higher hit dice?

To use a mathematical analogy, suppose that the satisfaction the Displacer Beast derives from feeding is the square of the hit dice. So a player, or monster that the Displacer Beast feeds on, that is 3rd level or three hit dice, provides nine times as much satisfaction to the Displacer Beast as a 1st level or one hit dice monster. He needs to eat nine first-level players to get the same satisfaction as one 3rd level monster.

The Displacer Beast then, rather than killing a party, encourages them to capture high hit dice monsters (say, a couple of Ogres that "stole and item from him") and bring them to him. The Players need not know that the Displacer Beast is using the party to feed his evil hunger.

The Displacer Beast may promise them rewards for doing so, and may be a reliable source of information, so the players acquiesce to the Displacer Beast's requests that they capture and deliver monsters to him. Eventually, however, the players should discover why the Displacer Beast is doing that, or they get to a sufficiently high level that the Displacer Beast views them as a tasty meal.

To protect the Displacer Beast from harm, at least initially, I would suggest that the Displacer Beast be able to create a field of darkness around itself, from which it parlays with the adventurers. Hints as to who is speaking from the darkness may be dropped, by occasionally having a tentacle wave from the darkness, and allow the dispel magic, light or dispel darkness spells to interfere with this creature's field of darkness ability.
