Wraith Vine Bramble (5e Environment)
From D&D Wiki
Wraith vine bramble
Wraith vine brambles are large patches of dull-yellow brown vines that commonly span areas of around 85 acres, growing in areas where the veil between the material plane and the shadowfell is particularly thin. Wraith vine chokes out all other life in the area it inhabits, draining nutrients and moisture from the soil and parasitizing large trees. As wraith vines spread so to does the weak point in the veil, getting thinner and thinner as native creatures from the shadowfell begin to spill into the material plane to cause chaos and misery.
unstoppable growth Wraith vine brambles are unstoppable unless either the veil is repaired, or the central mass of the bramble is destroyed. a Wraith vine bramble's central root mass has 196 health points, AC 11, vulnerability to fire damage and immunity to psychic and necrotic damage.
