  • Horrific Appearance. Any humanoid that starts its turn within 30 feet of the fachan that can see it must make a DC 10 Wisdom saving throw. On a failed save, the creature is frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if the fachan is within line of sight, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to the fachan’s Horrific Appearance for the next 24 hours. Unless the target is surprised, the target can avert its eyes and avoid making the initial saving throw. Until the start of its next turn, a creature that averts its eyes has disadvantage on attack rolls against the fachan.
  • Poor Depth Perception. The fachan has disadvantage on any attack roll against a target more than 30 feet away.
  • Standing Leap. The fachan’s long jump is up to 30 feet and its high jump is up to 20 feet, with or without a running start.


  • Multiattack. The fachan makes two attacks with its Flail.
  • Flail. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) piercing damage.
  • Rock. Melee or Ranged Weapon Attack. +9 to hit, range 60/240 ft., one target. Hit: 22 (3d10 + 6) bludgeoning damage.
  • Deadly Leap. If the fachan jumps at least 15 feet as part of its movement, it can then use this action to land on its feet in a space that contains one or more other creatures. Each of those creatures must succeed on a DC 14 Strength or Dexterity saving throw (target’s choice) or be knocked prone and take 14 (3d6 + 4) bludgeoning damage. On a successful save, the creature takes only half the damage, isn’t knocked prone, and is pushed 5 feet out of the fachan s space into an unoccupied space of the creature’s choice. If no unoccupied space is within range, the creature instead falls prone in the fachan s space.


The fachan is a monstrous creature that roams the rugged hills and mountains, known for its twisted and grotesque appearance. It stands at a towering height of ten feet, with a single leg positioned centrally beneath its body. Its wiry black hair sprouts from its head, and a tuft of tough hair rises from the top. The fachan possesses a single eye set in the middle of its face, and its countenance is black-faced and fearsome. It has a single arm protruding from its chest.

Fachans make their lairs in desolate and barren mountains, often inhabiting caves or abandoned stone cottages scattered across the rugged landscape. They prefer to dwell in isolated areas, far from civilized settlements. Fachans thrive in habitats that offer them ample opportunities to ambush their prey.

Fachans are carnivorous creatures that subsist on a diet of meat, preying on creatures they can overpower. They are relentless hunters and rely on their surprise attacks to overwhelm their opponents. Fachans are known for their sadistic nature, often prolonging the suffering of their victims rather than dispatching them swiftly. They exhibit a preference for inflicting fear and torment upon their prey.

Fachans are solitary creatures, rarely seen together unless compelled by a more powerful entity. They are opportunistic hunters, lying in wait for lone travelers or ambushing isolated farmsteads. Fachans are particularly active at night or during inclement weather when visibility is low, using their keen hearing to detect the sound of approaching prey from miles away.

In combat, fachans rely on their formidable strength and agility. They can deliver powerful kicks or wield weapons such as clubs, flails, axes, or swords with deadly force. Their preferred tactic is to launch surprise attacks, overwhelming their opponents with brute strength. Fachans also possess the ability to hurl rocks at their foes, inflicting significant damage from a distance.

Fachan leaders are known as athachs and are similar in appearance, only larger and meaner. The chief difference is the deadly nature of their eye, which is capable of dropping a man with a mere glance.
