Assassin vine

Assassin vines are carnivorous ambulatory plants which strangle their prey.

Appearance
Assassin vines resemble typical, non-ambulatory vines, growing up to around 20 feet in length, with offshoots every six inches. They are poisonous to touch. In late summer, assassin vines produce bunches of fruit similar to grapes, though they are tough and have a bitter flavor.

Characteristics
Assassin vines are ambulatory ambush predators, waiting until its prey walks over it, then constricting and crushing them until lifeless. Once dead, assassin vines place their kill at their roots to be turned into fertilizer.

Assassin vines grow in warm environments, typically in jungles and underground near hot springs or volcanic vents.

Abilities

 * False Appearance: Assassin vines are indistinguishable from regular vines while they remain motionless.
 * Constrict: The assassin vine makes a melee attack, grappling its target and dealing moderate bludgeoning damage on a successful hit. The target takes considerable poison damage at the start of its turn while grappled.
 * Entangling Vines: The assassin vine animates other vines in a 15-foot square within 30 feet of itself. The vines create difficult terrain and attempt to restrain creatures within the area. The vines remain animated for 1 minute or until the assassin vine uses this ability again.

History
While exploring the Temple of the False Serpent on Urukayxl, the Mighty Nein, accompanied by Avantika and Jamedi Cosko, encountered a patch of subterranean assassin vines cultivated by the yuan-ti cult of Zehir.
