Wraith Weed (5e Creature)
From D&D Wiki
Large undead, chaotic evil
Damage Vulnerabilities fire
Jailer of Souls. Souls within the wraith weed cannot be communicated with and the person to which the soul belongs to cannot be revived by any means other than a wish spell, which either kills the wraith weed (if it only contained one soul) or takes away a fraction of its power. When the wraith weed is killed the souls of any evil-aligned creatures are destroyed, and any good or neutral aligned souls are freed of the urge for vengeance and allowed to rest in peace.
Flaming Wrath. If the wraith weed takes fire damage, it catches aflame, dealing an additional 4 (1d8) fire damage whenever it hits with a vine attack or whenever it is touched or a creature within 5 feet of hit hits it with a melee attack. It also takes 9 (2d8) fire damage at the start of each of its turns. The flame is extinguished if the wraith weed is fully immersed in water.
Vine. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 4 (1d6 + 1) bludgeoning damage, plus 2 (1d4) poison damage
Pollen Burst (Recharge 6). The wraith weed exhales pollen in a 20-foot cone. Each creature in that area must make a DC 17 Constitution saving throw, taking 18 (4d8) necrotic damage and 18 (4d8) poison damage on a failed save, or half as much damage on a successful one.
When a sentient humanoid dies with hatred or anger in its heart while near a wraith vine bramble, the bramble will consume it's flesh and soul alike, causing it to become a wraith weed, an ogre-sized mass of undead vegetation. The vine wraps around its skeletal remains to replace its tendons and muscle and the soul is trapped inside a cage of vines, its unquenched urge for vengeance fueling its hideous unnatural movements. The wraith weed hunts for more prey, dying just to be born again, consuming more souls so it can spread the reach of its hunt, until it can finally ascend from its wretched existence.
