Pit Vipers were considered for inclusion in Fallout but were ultimately cut. Not much information about what these creatures might have been like is available—the statblock and Knowledge here are purely speculative.

Bite. Melee weapon attack: +6 to hit, reach 10 ft., one target. Hit: 11 (2d6 + 4) piercing damage, and the target must make a DC 12 Constitution saving throw. On a failed save the target take 10 (3d6) poison damage and is poisoned for 1 minute. The poisoned target is incapacitated while it hallucinates. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. On a failed save, the target takes half as much damage and isn’t poisoned.

Constrict. Melee weapon attack: +6 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage, and the target is grappled (escape DC 16). Until this grapple ends, the creature is restrained, and the pit viper can’t constrict another target.
