Adapter beasts superficially resemble displacer beasts: black with a cat-like form and two "tentacles" protruding from its back. However, adapter beasts are actually a completely separate kind of fey: it's theorised that, long ago, an ooze began mimicking the appearance of the terrible displacer beast, while keeping its amorphous qualities. As such, while an adapter beast physically resembles a displacer beast, its temperament, nature, and personality is vastly different.

Chaotic Schemers. Tricksters and trouble-makers that prefer slinking through the shadows than entering combat, an adapter beast forced to fight will often first try to flee. With no apparent escape route, their next trick is to flare their pseudopod "tentacles" and make a menacing display similar to that of a displacer beast, hoping to scare off potential predators.

Unknown Origins. While true displacer beasts have always been found in the feywild, adapter beasts appeared suddenly and without a clear history of where they came from. As they clearly have ooze-like qualities, the most popular theory is that adapter beasts were sewn into the feywild by worshippers of Juiblex, the demon lord of slimes and oozes. Given adapter beasts' mostly benign nature, however, even practitioners of this theory wonder at the reasoning behind the creation of such a creature.

Clever to a Fault. While they cannot speak, natives of the feywild are sure that adapter beasts understand more than they ought to: if a traveller mentions that a favourite trinket is stored safely in their pack, that trinket will disappear despite all precautions; if food or other resources are placed in a locked chest, the chest will be unlocked rather than broken, and its contents stolen. However, with such intelligence comes certain quirks--adapter beasts have been known to inadvertently put themselves in danger by venturing too close to strange creatures and places, their curiosity sometimes leading to their injury or death.
