  • Undead Fortitude. If damage reduces the zombie snake to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie poisonous snake drops to 1 hit point instead.


  • Bite. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 1 piercing damage, and the victim must make a DC 13 Constitution saving throw, taking 9 (2d8) points of poison damage on a failed save, or half as much on a successful save. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for one hour, even after regaining hit points, and is paralyzed while poisoned in this way.


Poisonous zombie snakes are undead serpents that deliver a deadly bite. The tiny asps are created using vipers. Their bodies often show the wounds that caused their deaths. Necromancers and other evil sorcerers occasionally animate entire barrels of the serpents to provide added defenses for their homes.
