  • Familiar. The sluagh can serve another creature as a familiar, forming a telepathic bond with its willing master. While the two are bonded, the master can sense what the sluagh senses as long as they are within 1 mile of each other. While the sluagh is within 10 feet of its master, the master shares the sluagh’s Magic Resistance trait. At any time and for any reason, the sluagh can end its service as a familiar, ending the telepathic bond.
  • Flyby. The sluagh doesn’t provoke opportunity attacks when it flies out of an enemy’s reach.
  • Harmed by Running Water. The sluagh takes 20 acid damage when it ends its turn in running water.
  • Incorporeal Movement. The sluagh can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.
  • Sunlight Hypersensitivity. The sluagh takes 20 radiant damage and has disadvantage on attack rolls and ability checks when it starts its turn in sunlight.
  • Undead Nature. A sluagh doesn’t require air, food, drink, or sleep.


  • Talons. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 1 slashing damage plus 2 (1d4) necrotic damage.


You see a vast flock of black ravens twined about with undulating shadows. Closer inspection reveals that the great birds look more like wretched thin shades of their previous selves, with gnarled talons similar to the blackthorn’s barbs for hands and feet, and wings of dusty smoke.

The sluagh (sloo-AH), also known as the “host of the dead,” are harbingers of the Unseelie Court. These malevolent entities are believed to be fallen angels who roam the midnight skies, seeking out lost souls and causing sickness and death in animals.

Sluagh have the ability to approach and pick up individuals from any direction, transporting them through the air to distant locations. While they might occasionally rescue humans from perilous situations, their intentions are typically sinister.

Sluagh are believed to be the souls of the dead flying through the air. They are associated with the feast of the dead, which is also considered the festival of the fairies. These entities are thought to be able to transport people from one island to another, further fueling their reputation as dangerous beings.

They serve as minions or messengers for more powerful unseelie fey, carrying out their sinister commands. Sluagh are known to spread sickness and fear, and they are often encountered in areas associated with death, darkness, and the unknown.

Sluagh replenish their ranks through murderous swarms, descending like locusts on those foolhardy enough to travel alone at night. The dead are transformed into tiny winged fey that look vaguely reminiscent of their forms in life.
