Vengas (5e Creature)
From D&D Wiki
Small beast, unaligned
Charge. If the vengas moves at least 10 feet straight toward a target and then hits it with a bite attack on the same turn, the target takes an extra 3 (1d6) piercing damage.
Death Cloud. When the vengas dies, it explodes to release a cloud of violet, poisonous gas out to a radius of 5 feet. This cloud lasts for 1 minute, or until a strong breeze disperses it. A creature that starts its turn in the cloud or enters it on its turn takes 3 (1d6) poison damage.
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) piercing damage.
A vengas appears as an overgrown insect with a golden-brown carapace, four black ant-like legs, a pair of black antenna, and two dimly glowing green eye-like organs it uses to see. Unusual for an insect, it has the capability to gallop and charge at high speed towards its prey, in a manner reminiscent of a pouncing panther.
A vengas is usually found in small groups of others of its kind, and together they are overwhelmingly aggressive towards anything they come across. When one vengas dies, its corpse bursts with a poisonous gas that doesn't affect its peers. The released poison can help the rest of its kin take down the predator that killed it.
