  • Bite. Melee Weapon Attack: +3to hit, reach 5 ft., one target. Hit: 10 (2d8 + 1) piercing damage, and the target must make a successful DC 14 Constitution saving throw or become poisoned. While poisoned this way, the target is blind and takes 7 (2d6) poison damage at the start of each of its turns. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself with a success.


Greenish liquid drips from the dagger-length fangs of this 20-foot-long monstrosity. They show little fear.


Human Hunters. This giant venomous snake is known as one of the most lethal serpents, and one of the few that will attack an adult human. One bite from the black viper can kill a healthy human in seconds, and its tough hide makes it difficult to dispatch quickly.

Jungle Bred. A black viper grows quickly in its jungle home, and some even venture into the savanna to terrorize antelopes and young giraffes.

A full-grown black viper is up to 30 feet long and weighs up to 400 pounds.

Famous but Rare Venom. A dose of its viscous green venom is known to fetch as much as 2,500 gp on the black market, but it is rarely available.
