Mantrap

Mantraps are large carnivorous flytrap-like plants that grow in wet, tropical environments.

Appearance
Mantraps appear similar to ferns, with three to four large leaves spread outward, able to snap shut vertically forming a maw. They are largely sessile, but are able to uproot and crawl slowly across the ground.

Abilities

 * False Appearance: Unless the mantrap moves, it appears indistinguishable from an ordinary tropical plant.
 * Attractive Pollen: When the mantrap detects a creature nearby using its tremorsense, it can release a cloud of yellow pollen out to a radius of 30 feet. Each beast and humanoid within that cloud must make a DC 11 Wisdom saving throw. On a failure, it attempts to move as close to the mantrap as possible. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on a success. A mantrap can only release this cloud of pollen once per day.
 * Engulf: The mantrap swallows a Medium or smaller creature within its reach. Such a creature is restrained within its leafy jaws, and takes acid damage at the start of each of its turns. A mantrap can only engulf one creature at a time.

While traveling through the Labenda Swamp to secure The Gentleman's safe house, the Mighty Nein encountered several mantraps. Calianna attempted to burn one with a Fireball, which it survived but was quickly dispatched with the help of the rest of the party. They later encountered another, which their guide Febron Keyes nearly walked into after succumbing to its pollen. Calianna was able to save him by Levitating him above it.

After attempting to intimidate the jungle of the Whitedawn Lagoon into allowing the Mighty Nein to pass through unimpeded, Fjord immediately stepped into a mantrap, which instantly closed around him. Yasha Nydoorin was able to wrench the leafy jaws open, allowing Fjord to cut his way out using Dwueth'var.

While traveling through the Rifenmist Jungle, a group of rookie adventurers encountered a Qoniira ruin that was surrounded by numerous mantraps.
