  • Jungle Camouflage. The constrictor has advantage on Dexterity (Stealth) checks made to hide in jungle terrain.
  • Poisonous Leaves. The skin of the constrictor is embedded with vines and poisonous leaves that burn on contact. A creature that isn’t a Construct or Undead that touches the constrictor or hits it with a melee attack while within 5 feet of it takes 7 (2d6) poison damage.
  • Urushi Blight. A creature infected with this disease manifests symptoms within 1d4 hours, which includes the gradual spread of a painful, itching rash that develops into inflamed and blistered skin over the course of the first day. Until the disease is cured, the infected creature has disadvantage on Constitution saving throws made to maintain concentration on a spell, and it has disadvantage on Dexterity and Charisma saving throws and ability checks. At the end of each long rest, the infected creature must make a DC 15 Constitution saving throw. If it succeeds on two saving throws, it recovers from the disease.


  • Multiattack. The constrictor makes two Bite attacks or one Bite attack and one Poisonous Constriction attack.
  • Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., one creature. Hit: 14 (2d10 + 3) piercing damage.
  • Poisonous Constriction. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 12 (2d8 + 3) bludgeoning damage, and the target is grappled (escape DC 15). Until this grapple ends, the target is restrained and takes 10 (3d6) poison damage at the start of each of its turns, and the snake can’t use Poisonous Constriction on another target. Each time the target takes this poison damage, it must succeed on a DC 15 Constitution saving throw or contract the urushi blight disease (see the Urushi Blight trait).


A constrictor snake enrobed in a sleeve of deadly leaves and vines slithers along the forest floor.

A melding of plant and beast, the urushi constrictor is driven by impulse and irritability. They were once pythons who coiled among the urushi vine, a parasitic plant that causes extreme rashes in most animals and humanoids that touch it. Eventually these pythons bonded with the vine, gaining a hazardous defense mechanism that augments their crushing hug.

Jungle Wanderers. Cursed by a constant itching, these snakes roam their territories, unable to maintain a lair for more than a few days. They can be tracked by the knowledgeable, for in their paths they leave seedlings of the urushi vines bonded to them. Great care must be taken when following such a path, as the swift-sprouting vines are just as toxic as the constrictor’s noxious embrace.
