Special Traits

  • Damage Transfer. While it is grappling a creature, the lurker above takes only half the damage dealt to it, and the creature grappled by the lurker above takes the other half.
  • Keen Scent. The lurker above has advantage on Wisdom (Perception) checks based on scent.
  • Sunlight Sensitivity. While in sunlight, the lurker above has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.


  • Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 17 (3d8 + 4) bludgeoning damage and the target is grappled (escape DC 15) and the lurker above cannot grapple or use its Slam attack on another target.
  • Smother. The lurker above wraps itself around one grappled creature of Large size or smaller, completely enclosing it. The grappled target is restrained, blinded, no longer able to speak or use spells with verbal components, and at risk of suffocating. At the start of each of the target’s turns, the target takes 17 (3d8 + 4) bludgeoning damage.


A black manta ray-like creature three times the size of a normal human flies toward you. Its body is black changing to gray on its inside or underbelly.

The lurker above is a subterranean carnivore that preys on any living creatures that enter its territory.

These creatures are extremely territorial and are never encountered with others of their kind. Mating habits among lurkers are unknown to sages as no two of these creatures have ever been encountered together. A typical lurker above has a hunting territory of several square miles.

A lurker above waits for its prey, clinging to the ceiling, roof, or other such overhangs. When prey passes beneath it, the lurker above drops from its hiding place and wraps itself around its prey.

Lurker Below

The lurker below is an aquatic variety of lurker above that makes its lair in any body of water and in any climate (though it rarely lairs in extremely cold climates).

Lurkers below are pale blue or black in color and are often mistaken for giant manta rays. Lurkers below cannot fly but have a swim speed of 40 feet. They are otherwise identical to their land-based counterparts detailed above.
