Welcome to the A.T.L.A.S. database, your premier resource for understanding extraordinary creatures: with this entry we delve into DnD 5e‘s mysterious realm to uncover the enigmatic Doppelganger‘s secrets. Join us as we provide a concise yet comprehensive description of this shape-shifting entity, explore its remarkable abilities, and assess its threat level.

Basic Description: 

The Doppelganger is a mesmerizing creature of illusion and deception. It possesses a humanoid form, devoid of distinct features, enabling it to assume the appearance of any individual it encounters. This uncanny ability to mimic others grants them unparalleled skills in infiltration and subterfuge, rendering them virtually indistinguishable from their chosen guise.

Abilities: 

The Doppelganger’s most formidable power lies in its shape-shifting prowess. It can seamlessly adopt its chosen target’s physical form, mannerisms, and even memories, making it a formidable manipulator and infiltrator. Its natural empathy enables it to discern emotions, further aiding in mimicry. Doppelgangers also possess innate combat abilities, including a knack for surprise attacks and an uncanny aptitude for blending into their surroundings.

Threat Level Assessment: 

The threat level of a Doppelganger varies based on its intentions. While they may prefer subterfuge and manipulation over outright confrontation, their ability to exploit trust and assume the identities of others poses significant risks. The Doppelganger’s elusive nature and talent for sowing chaos make them a considerable threat to individuals, organizations, and even governments even though they might not be strong in a direct confrontation. Their Challenge Rating (CR) is relatively low, reflecting their combat proficiency and deceptive capabilities: en encounter with a Doppleganger can be considered “Hard-Deadly” for a group of 4 players with a level 2 or lower.

Characteristics:

Doppelgangers, mysterious and enigmatic, are monstrous humanoids with the extraordinary ability to assume the appearance of other humanoid creatures. This shapeshifting power grants them the uncanny ability to mimic the physical attributes of their chosen targets. In their true form, Doppelgangers manifest as tall, gray-skinned humanoids with formless faces, bulging eyes, and an unsettling, physically deceptive appearance.

While Doppelgangers possess exceptional shapeshifting prowess, there are limitations to their mimicry. They cannot replicate languages, memories, or personalities, thus preserving their own distinct nature. However, their ability to detect thoughts and immunity to mind-altering spells give them a strategic advantage in their clandestine endeavors.

Behaviour and Environment

Doppelgangers in DnD 5e are cunning creatures, characterized by their lazy yet opportunistic nature. They often exploit their shapeshifting abilities to engage in surprise attacks and ambushes, leaving their adversaries bewildered and disoriented. The origins of the Doppelgangers are believed to be rooted in an artificial race created by the “Creator Race” known as the Batrachi, who designed them as spies and assassins.

Operating in small groups, Doppelgangers infiltrate societies by seamlessly assuming the forms and lives of their chosen targets. Their preferred modus operandi involves replacing individuals for personal gain, sowing chaos, and exacerbating organizational power struggles. Consequently, their presence instills paranoia and suspicion among other races, as their ability to impersonate anyone poses a significant threat.

While Doppelgangers may engage in casual mating, their family units are non-existent, with females raising their offspring independently. Their unique abilities and malevolent nature have earned them a notorious reputation, making them feared by other races and widely employed by various creatures in times of scarcity, where they serve as spies, assassins, and pawns in power struggles.

Notable Doppelgangers include Bonnie, a cunning leader of a Doppelganger gang notorious for their subversive activities. Hlaavin, a half-illithid Doppelganger, assumed a prominent role as a leader within their own enigmatic ranks. Jacob, a Doppelganger with exceptional skills, was involved in a daring rescue mission that showcased the full extent of their shapeshifting prowess.

Waterdeep, a bustling metropolis, is home to a clandestine group known as The Unseen, consisting of shapeshifters, including Doppelgangers. Their covert operations and the intricate web of deceit they weave have shaped the city’s delicate balance of power.

Now, let us explore the strategies and methods employed by the A.T.L.A.S. organization when confronting these enigmatic beings.

Confronting a Doppelganger

Confronting a Doppelganger requires a keen eye and a careful approach. The following techniques have proven effective in identifying and neutralizing these shape-shifting adversaries:

1. Observation and Analysis: Doppelgangers excel at blending into their surroundings. The key lies in keen observation and astute analysis. Look for subtle inconsistencies in behavior, speech patterns, or physical traits that may betray their true nature. We suggest you to pay attention to their eyes, as Doppelgangers often struggle to imitate the depth and emotion of genuine human eyes perfectly.

Example: In a recent case handled by A.T.L.A.S., a Doppelganger had infiltrated a noble’s court, assuming the identity of a trusted advisor. In this case, our Agents successfully identified the imposter by noting a slight hesitation in its gestures and a subtle mismatch in its reactions.

2. Divination Magic: Utilize divination spells and magical abilities to uncover the true form of a suspected Doppelganger. Spells like True Seeing or Detect Thoughts can pierce through their illusions and reveal their true identity.

Example: A.T.L.A.S. operatives engaged a suspected Doppelganger who had infiltrated a high-ranking political office. By casting True Seeing, they exposed the creature’s true form, enabling them to take swift and decisive action.

3. Teamwork and Communication: Collaborate closely with allies and share information about potential Doppelganger sightings. Establish a network of trustworthy individuals who can confirm or refute suspicions based on their own encounters. Effective communication and coordination are vital when dealing with these masters of disguise.

Example: A.T.L.A.S. maintains an extensive network of informants and operatives, allowing them to pool information and verify suspected Doppelganger sightings. This collective effort enables the organization to identify patterns and track the movements of these elusive beings.

4. Ensnarement and Isolation: Doppelgangers often work in small groups to achieve their nefarious goals. You can gain the upper hand by isolating them from their allies and exploiting their vulnerability. Use magical barriers, traps, or physical restraints to restrict their ability to escape or transform.

Example: In a covert operation by A.T.L.A.S., operatives successfully trapped a group of Doppelgangers inside a magically sealed chamber. Without the ability to assume different forms or call for reinforcements, the operatives swiftly neutralized the threat.

Remember, confronting a Doppelganger requires both caution and astuteness. Their deceptive nature demands a meticulous approach. By employing careful observation, divination magic, teamwork, and ensnarement tactics, A.T.L.A.S. agents have consistently proven their ability to counter the threat posed by these shape-shifting adversaries.
