Born on leathery wings, the arcanaphage superficially resembles an oversized bat. Unlike an actual chiropteran, however, it doesn't have back legs to speak of and is likewise without eyes. Instead, a long and prehensile tail curls from its hind and ends with an ivory hook. The monstrosity's front end is just as dangerous too with a pale horn protruding from the creature's forehead. It is this second growth that allows the arcanaphage to 'see' the world around it via the ebbs of magic instead of mere echolocation. An arcanaphage's skin is usually toxic green in color, though yellow specimens have been reported.

Magic Eater. The arcanaphage isn't interested in eating meat or plants. Instead, the winged horror devours magic to sustain itself. The species usually nests in arcane ruins, feeding off of the ambient magic as it decays. However whenever a fresh source of magic, such as a party of adventurers, enters an arcanaphage's hunting grounds it is quick to attack. Often the monstrosity will target the group's spellcasters first and snatch them with its hook tail to be carried off and drained of power somewhere safter. Because of this, and their innate protection against arcane forces, these creatures are sometimes called wizardbanes.
