Doppelganger Plant (5e Creature)
From D&D Wiki
Huge plant, chaotic evil
Pods. A doppelganger plant has 10 (3d6) pods, each of which can hold the life essence of a single humanoid creature. Pods can be targeted (AC 10; 10 hit points). Damage dealt to a pod is subtracted from the plant's total hit points. When a pod is destroyed, any soul that is stored inside is returned to its body.
Mind Link. The podlings or a doppelganger plant are extensions of itself, and it can communicate with its podlings over any distance. The plant sense what each of its podlings sees and has access to the knowledge and memories of the podlings. The doppelganger plant is proficient in any skill a podling is proficient in and can make Wisdom (Perception) checks through its podlings.
Direct Podlings. The doppelganger can command up to 3 podlings take an action.
Mind Bondage. The doppelganger plant targets one sleeping or unconscious creature within 1 mile. The target must succeed on a DC 14 Wisdom saving throw or charmed by the doppelganger plant. The charmed target is under the control of the plant and can't take reactions. Whenever the charmed target takes damage, the target can repeat the saving throw. On a success, the effect ends. The doppelganger plant must maintain concentration while using Mind Bondage (as if concentrating on a spell). A target that makes a successful saving throw against Mind Bondage is immune to further attempts for 24 hours. After 1 hour, the doppelganger plant tries to draw the essence of a charmed creature into one of its pod. The charmed creature makes an Intelligence check contested by the doppelganger plant's. If the doppelganger plant wins, it traps the soul and no longer needs to maintain concentration, and the creature becomes a podling. If the charmed creature wins, the doppelganger plant must wait an hour before trying to absorb its soul.
Disorient (Recharge 5-6). The doppelganger plant mentally attacks the minds of nearby creatures. Each creature in 15 feet of the doppelganger plant that is not a podling must make a DC 14 Wisdom saving throw. On a failed saving throw, the creature become stunned for 1 round and take 10 (3d6) psychic damage, or half damage on a success.
The origins of this horrific plant are utterly unknown, as is much important information about it, but sightings of falling stars often predate its appearance. A doppelganger plant appears as a thick tangle of vines with numerous pods hidden in the thicket. These pods are the source of the wicked creature’s intelligence. They also serve as its main form of self defense as they are able to dominate the minds of others and make them serve the plant's will.
The Podlings. Creatures whose souls are trapped in a pod of a doppelganger plant become podlings. The doppelganger plant assumes control of their bodies, impersonating them. A doppelganger plant can have as many podlings as it has pods, and easily control all during routine actions. Controlling multiple podlings during periods of stress, such as when its body is engaged in combat or endangered, is more difficult. A podling retains its original stat block but uses the doppelganger's Intelligence, Wisdom, and Charisma scores. Player characters that become a poddling typically retain all class abilities and racial powers. The doppelganger sustains itself with the essence of a podling. At the end of each short or long rest the creatures hit point maximum is reduced by 3 (1d6), as the doppelganger plants hollows them out from the inside out. Creatures reduced to 0 hit points by this effect are reduced to empty husks and slain.
