Welcome to the A.T.L.A.S. database, your comprehensive source for information on extraordinary creatures: today, we will analyze the Chuul from the DnD 5e.

Basic Description:

The Chull is a monstrous crustacean creature, reminiscent of a colossal crab with jagged exoskeleton plates. Its hulking form stands at an intimidating height, its pincers ready to seize any unfortunate prey that crosses its path. Covered in a rugged, armored carapace, the Chull possesses an otherworldly resilience that allows it to withstand even the most potent attacks.


The Chull possesses a range of formidable abilities that make it a force to be reckoned with. Its immense strength grants it the power to crush opponents with its mighty claws. With an exoskeleton capable of deflecting blows, it can endure extended battles. Moreover, its ability to burrow through the earth and rock makes it a relentless pursuer, capable of surprising its victims with lightning-fast ambushes.

Threat Level Assessment:

The Chull’s threat level is evaluated based on its Challenge Rating (CR) of 4. Its immense size, armored defense, and powerful pincers make it a formidable opponent, especially for low-level parties. Engaging a Chull requires a strategic approach, exploiting its vulnerabilities and employing hit-and-run tactics. High mobility, ranged attacks, and knowledge of its weak points are essential for survival.

Amphibious. The chuul can breathe air and water.

Sense Magic. The chuul senses magic within 120 feet of it at will. This trait otherwise works like the detect magic spell but isn’t itself magical.


Multiattack. The chuul makes two pincer attacks. If the chuul is grappling a creature, the chuul can also use its tentacles once.

Pincer. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage. The target is grappled (escape DC 14) if it is a Large or smaller creature and the chuul doesn’t have two other creatures grappled.

Tentacles. One creature grappled by the chuul must succeed on a DC 13 Constitution saving throw or be poisoned for 1 minute. Until this poison ends, the target is paralyzed. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Characteristics of Chull

Chuuls, also known as Chulls, are fearsome creatures that combine the features of crustaceans, insects, and serpents. Towering at around 8 feet, these yellow-green lobsters weigh approximately 650 pounds. Their formidable appearance includes four long legs, two large and powerful claws, a sturdy exoskeleton, a fan-like tail, and menacing paralyzing tentacles surrounding their mouths. Don’t be fooled by their monstrous form, as Chuuls possess an intelligence that allows them to exhibit cunning and strategic behavior.

Behavior and abilities

Chuuls are driven by two primary motivations: the desire to be left alone and the insatiable urge to feast upon unsuspecting humanoids. They employ their intelligence to set traps and lay ambushes, utilizing their racial memory of hating and hunting humanoids. In combat, Chuuls employ their enormous claws to grab and pierce their victims, inflicting devastating damage. The paralyzing tentacles are another weapon in their arsenal, capable of immobilizing their prey with a potent venom.

These formidable creatures possess exceptional vision, allowing them to see clearly even in complete darkness. Their resistance to poisons grants them an immunity that adds to their already fearsome nature. While Chuuls are amphibious, they are not proficient swimmers: they prefer to combat on land or in shallow water, where they can lie submerged and execute surprise attacks with deadly precision.

Environment and Lairs

Chuuls are known to create intricate lairs by excavating lake bottoms and constructing interconnected circular rooms. Within these lairs, they hoard trophies from their humanoid victims, collecting shiny armor, jewelry, and even skulls as macabre tokens of their conquests. These hoards are often stored in a dedicated room, a testament to their predatory prowess.

In various aquatic habitats, Chuuls can be encountered in swamps, jungle lakes, temperate marshes, underground bodies of water, sewer tunnels, and even shipwrecks. Their ability to adapt to different environments allows them to thrive in a wide range of locations, making them a formidable threat wherever they are encountered.

Confronting the Chull

Encountering a Chull is a perilous situation that requires caution and strategic planning. To effectively confront these monstrous creatures, exploiting their weaknesses while capitalizing on their predictable behaviors is essential. Here are a few tactics to consider when facing a Chull:

  1. Exploit their limited swimming abilities: As Chuuls are not adept swimmers, luring them into deep waters can limit their mobility and give you an advantage.
  2. Disrupt their ambush tactics: Chuuls are known for their ambushes and traps. Remain vigilant in areas where they are likely to lie in wait.
  3. Leverage ranged attacks: Chuuls excel in close combat but can be less proficient at dealing with them. Use ranged weapons or spells to keep your distance and wear them down from afar.


Remember, it is crucial to approach the Chull with adequate preparation and respect for their formidable capabilities. Engaging in combat with these creatures should only be done with the utmost caution and as a last resort.
