Strangler heart

Strangler hearts are creatures found in Appalachia.

Background
Previously encountered by the Free States, the hearts are known for infesting living creatures with vines and amassing groups of hostile creatures.

Biology
Strangler hearts are large, mutated, carnivorous flowers. They have three massive petals thick enough to close and use for protection from outside attacks. The center of the flower holds a gaping humanoid-like mouth surrounded by jagged teeth. A long vine-like tongue writhes from the open mouth. The hearts have an innate ability to use their vines to infest other living creatures and form diverse bands.

Gameplay attributes
While appearing as non-hostile to players, strangler hearts are still able to directly inflict damage. When attacked, the heart will spit out a toxic gas that gives +6 rads/second. If further damaged, it will close and call for reinforcements.

When closed, strangler hearts are immune to damage and are able to summon waves of strangler mirelurks and strangler feral ghouls. The hearts reopen once the enemies are defeated. Once below a quarter of its total Hit Points, stranger hearts will summon a strangler mirelurk queen or a strangler Grafton Monster.
