  • Eerie Presence. Crunching footsteps and strange mists increase within 30 feet of the fear liath. Anyone within 30 feet of it has disadvantage on Wisdom (Perception) checks and Intelligence (Investigation) checks that rely on sight and sound.
  • Innate Spellcasting. The fear liath’s innate spellcasting ability is Wisdom (spell save DC 13). It can innately cast the following spells, requiring no material components:


  • Multiattack. The fear liath uses its Terrifying Gaze and makes two Claw attacks.
  • Claw. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 7 (1d6 + 4) slashing damage plus 3 (1d6) psychic damage.
  • Terrifying Gaze (Recharge 5-6). The fear liath fixes its gaze on a creature within 30 feet of it. The creature must succeed on a DC 13 Wisdom saving throw or be frightened for 1 minute. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.


The fear liath is a massive, humanoid creature standing over ten feet tall with a gaunt frame. Its skin is dark and leathery, blending seamlessly with the rocky landscape, and its long, sinewy arms end in claw-like fingers. Despite its intimidating size, it moves with uncanny stealth. Its presence is often accompanied by the sound of crunching gravel as it treads lightly through the mist.

The fear liath, known as the Big Grey Man, is a mysterious and elusive creature that haunts the mist-covered peaks. It is rarely seen but often felt, leaving climbers with a sense of unease as they traverse the rocky terrain. The creature seems to be drawn to misty peaks, and its ability to blend into the surroundings makes it a master of camouflage.

The fear liath is an enigmatic creature, rarely seeking direct confrontation. Instead, it utilizes its chilling gaze and terrifying presence to frighten off intruders and maintain its domain. It preys upon the fears and vulnerabilities of climbers and hikers, causing them to become disoriented and afraid. The fear liath is not inherently aggressive but will defend its territory fiercely if provoked.

The fear liath’s existence is shrouded in mystery, with sightings primarily based on eyewitness encounters and a general feeling of unease around the mountain. Some believe it to be a guardian spirit of the mountains, while others consider it a malevolent force that feeds on the fear of those who wander into its domain.
