The most dangerous thing about the creature, however, is its death gaze. Any creature that approaches within 4 hexes of the beast is in danger of catching the catoblepas' eye, whereupon a saving throw must be made or the creature's chest will seize tight with horror and the individual will quite literally die. The death will be equivalent to -11 hit points, so that a death's door spell will restore the victim.
As well, the catoblepas' tail features a bony club upon its end, which is fixed with ridges. The tail is structured so that the tail will snap like a whip when it hits a defender, causing it to hit very hard. If the tail hits and stuns, the defender should be considered profoundly stunned for two rounds rather than one.
The existence of the creature, including its ability to procreate others of its kind, has long been a source of contention. It is believed that the catoblepas was the result of a beast-making experiment gone wrong; some say that the catoblepas came from the lower planes of existence and that it is really a demon. Whatever the case, the discovery of these creatures in an area (a knowledge that includes the probability that there are others) brings consternation to many, while the eradication of the beasts will often rely on willing outsiders prepared to risk the catoblepas' death gaze.
