  • Acid Mucous. The feulk generates an acidic mucous from its tentacles; any creature grappled by the feulk suffers 2 (1d4) points of acid damage per round they are grappled. This damage persists each round after the creature is released until it is thoroughly washed with water (immersion or soaking for at least 1 round). In addition, this mucous impairs movement, causing disadvantage on all attack rolls and dexterity checks and saves, until washed off.


  • Multiattack. The feulk makes three tentacle attacks every round.
  • Tentacle. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 8 (1d8+4) bludgeoning damage and target is grappled and restrained unless it succeeds at a Strength save (DC 15). Creatures thus grappled suffer additional 8 (1d8+4) bludgeoning damage at the beginning of each of the feulk’s turns, as well as acid mucous damage, and are subject to a bite attack. The creature may attempt a new saving throw at the end of each of its turns, freeing itself with a success.
  • Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d6+4) piercing damage. The feulk may only bite creatures that are currently grappled by its tentacles.


The feulk dwell in deep forests and jungles. Their bodies are amorphous masses of tissue clinging to the tops of trees through a series of adhesive secretions. The body has no definable shape, stretching from tree stem and branch in large globs. Though they cannot move, they do grow in their nests, often leaving one area for another. Older, dying sections of the feulk tend to fall over, lying on the ground or sticking to the trees. They have long arm-like, fully retractable tendrils they project from their body. These tendrils are similar to vines; complete with a hardened covering (the drying mucous) that resembles bark. The feulk are able to adapt to their surroundings changing color from green to brown and many shades thereby. They are not noticeable from the ground unless someone is experienced in finding these strange creatures. Their young are born spontaneously, emerging from the mucous. The vast majority die by falling to the earth, where they are eaten, though some are able to cling to birds and are carried off into the forest. They drop off when they come upon a suitable hunting ground, falling into the treetops where they cling and slowly grow, feeding at first on insects and birds but slowly moving up the food chain.

Ambush Predators. The feulk cling to their treetop homes, waiting for creatures to pass over, under or near their vines. They prefer to wait until they can strike with several vines at once, but if their victim is moving away, they strike with whatever they can. They wrap their vines around the prey and proceed to lift them into the heights of the trees to feed upon them.
