Keen Smell. The catoblepas has advantage on Wisdom (Perception) checks that rely on smell. Stench. Any creature other than a catoblepas that starts its turn within 30 feet of the catoblepas must succeed on a DC 16 Constitution saving throw or be poisoned until the start of the creature's next turn. On a successful saving throw, the creature is immune to the stench of the catoblepas for 1 hour.
