  • Stunning Ugliness. The catoblepas is so shockingly ugly that just glimpsing one can blind the viewer. Characters fighting a catoblepas must either avert their eyes and take tactical disadvantage on attack rolls against the catoblepas or make a DC 15 Constitution saving throw before making their attack roll. Failure on the saving throw means the character is blinded until the start of his or her next turn. Anyone who rolls a lower initiative result than the catoblepas must attempt this saving throw immediately at the beginning of combat.


  • Multiattack. The catoblepas makes one Tail attack and one with its Rancid Breath (if available).
  • Tail Melee Weapon Attack: +6 to hit, reach 15 ft., up to 3 creatures in a 10-ft. square. Hit: 8 (1d10 + 3) bludgeoning damage and the target is forced prone.
  • Rancid Breath (recharge 5-6). Creatures within a 60 ft. cone emanating from the catoblepas must succeed on a DC 15 Constitution saving throw against poison or be stunned. Stunned creatures can repeat the saving throw at the end of each of their turns, recovering with a successful save. If a creature that is currently stunned by the catoblepas’ breath is stunned again by a second rancid breath attack, that creature immediately drops to 0 hit points.


The catoblepas is loathsome beyond description, with no positive qualities whatsoever. It resembles a bloated hippopotamus with a long, whip-like tail and a snakelike neck topped with the oversized head of a diseased warthog with bloodshot eyes. For all its ungainliness, its tail is tremendously quick and accurate when whipping around to strike at enemies anywhere near the creature.

The deadliest weapon of the catoblepas, however, is its rancid breath, which can leave creatures helplessly gasping for air, or even kill with too large a dose. Fortunately, its metabolism is so slow that it exhales only infrequently.
