Wenn

Keen Hearing. The Wenn has advantage on Wisdom (Perception) checks that rely on hearing.

Pack Tactics. The Wenn has advantage on an attack roll against a creature if at least one of the Wenn's allies is within 5 ft. of the creature and the ally isn't incapacitated.

Telepathic Link. The Wenn is telepathically linked to its god: the fearsome Wennbar. If the Wennbar calls for it, the Wenn will drop what it is doing and attempt to reach it immediately.

Food Delivery. The Wenn's focus isn't to kill any opponents, but rather to incapacitate them and deliver them as a sacrifice to the Wennbar. However, a lone Wenn cannot attack and is vulnerable when carrying food. It will not attempt this unless it has at least two other Wenn to cover its escape

Scratch. Melee Weapon Attack: +3 to hit, reach 5ft, one target. Hit: 4 (1d4 +2) piercing damage.

Paralyzing Sting. Melee Weapon Attack: +3 to hit, reach 5 ft., one creature. Hit: 5 (1d6 +2) piercing damage, and the target must make a DC 11 Constitution saving throw, taking 10 (3d6) poison damage on a failed save, or half as much damage on a succesful one. If the poison damage reduces the target to 0 hit points, the target is stable but paralyzed for 1 hour, even after regaining hit points.

Sonic Buzzing. The Wenn focuses its turn on rubbing its legs together to produce a buzzing sound. If at least three Wenn within 30 ft. are also producing Sonic Buzzing, any non-Wenn creature hearing it must make a DC 10 Constitution saving throw. On a failed save, the target falls unconscious for 1 hour until someone uses an action to shake the target awake.
