Multiattack

The yowler makes two attacks: one with its bite and one with its claws. It can use Yowl in place of a bite attack.

Bite

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage, and the target must succeed on a DC 12 Constitution saving throw or be poisoned until the end of its next turn.

Claws

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) slashing damage.

Yowl

The yowler lets loose a horrid scream. Each hostile creature within 30 feet of the yowler that can hear it must succeed on a DC 12 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the yowler's Yowl for the next 24 hours.
