Beedrill

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

Twinneedle. The Beedrill makes two poison sting attacks.

Poison Sting. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: (1d6 + 2) piercing damage, and the target must succeed on a DC 12 Constitution saving throw or take 2 (1d4) poison damage on a failed save, or half as much on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.
