So it turns out that catoblepas comes to us by way of Latin catōblepās from Ancient Greek katôbleps or katôblepon, and its plural in Latin is catōblepae, while its Ancient Greek plural is either katôblepes or katôblepones. Of all these, I like “catoblepes” best—much more than “catoblepases.” I’m going with it. Also, the accent is on the o: ca-toh-bleh-pahs, ca-toh-bleh-peez. And that’s one to grow on!
The catoblepas is largely a scavenger, whose loathsome presence befouls the environment around it; I guess it likes its food somewhat pre-decomposed. The foul-tempered monstrosity extends this preference to any edible trespasser who wanders into its territory—thus its Death Ray feature, which inflicts considerable necrotic damage on its target, enough to kill even a level 2 or 3 player character on a successful Constitution saving throw.
Catoblepes are classified as monstrosities, but they’re unaligned and have only beast-level Intelligence, around the level of a cat or dog. Their Strength and Constitution, however, are extraordinary, and their Dexterity is above-average as well. Their darkvision suggests that they’re crepuscular and/or nocturnal; you’re not likely to run across one in broad daylight. They combine above-average passive Perception with Keen Smell, giving them an effective passive Perception of 17 if you’re upwind of them. (more…)
