  • Aversion of Wood. If the gancanagh takes damage from a weapon made of rowan or mistletoe or is within 5 feet of a creature holding more than one pound of that wood, it has disadvantage on attack rolls and ability checks until the end of its next turn.
  • Fey Ancestry. The fey has advantage on saving throws against being charmed, and magic can’t put it to sleep.
  • Telepathic Bond. The gancanagh ignores the range restriction on its telepathy when communicating with a creature it has charmed. The two don’t even need to be on the same plane of existence.


  • Charming Touch. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: The target must succeed on a DC 16 Charisma saving throw or be charmed by the gancanagh for 1 minute. While charmed, the target is incapacitated and has a speed of 0. The charm effect ends if the gancanagh attacks the target, if the target takes any damage, or if the gancanagh uses a bonus action to end the effect.
  • Draining Kiss. The gancanagh kisses a creature charmed by it or a willing creature. The target must make a DC 15 Constitution saving throw against this magic. On a successful save, the creature can’t be charmed by the gancanagh for 24 hours. On a failed save, the creature takes 32 (5d10 + 5) psychic damage and is cursed, gaining a form of indefinite madness (“I only trust the gancanagh. And only I can see this special friend.”) that lasts until the creature is cured of the curse or dies.
  • Etherealness. The gancanagh magically enters the Ethereal Plane from the Material Plane, or vice versa.


Gancanaghs are male fey of extraordinary beauty. They have pointed ears and an otherworldly grace that sets them apart. Gancanaghs often carry unlit pipes.

Gancanaghs are sometimes referred to as the “Love-Talkers” due to their enchanting and gentle voices that mesmerize their targets. They are hedonistic creatures, reveling in pleasure and the pursuit of love. Gancanaghs are flirtatious, captivating those they encounter with their charm. While they enjoy the company of both men and women, they are especially fond of romancing young mortal maidens.

Gancanaghs are incorrigible flirts and often woo both mortals and immortals alike. However, despite their flirtatious nature, they tend to focus their attention on one individual at a time, courting and charming them before moving on to another. They crave excitement, enjoying the thrill of a new romantic conquest.

Once a mortal has been seduced by a gancanagh, they become hopelessly addicted to their presence, leading to tragic and sometimes even fatal consequences. To protect oneself from their allure, an amulet made from rowan and mistletoe, bound with an iron nail and a blood-soaked thread, is said to be effective.
