  • Horrific Appearance. Any humanoid that starts its turn within 30 feet of the bean-fionn and can see the bean-fionn’s true form must make a DC 13 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 bean-fionn 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 bean-fionn’s Horrific Appearance for the next 24 hours. Unless the target is surprised or the revelation of the bean-fionn’s true form is sudden, 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 bean-fionn.
  • Innate Spellcasting. The bean-fionn’s innate spellcasting ability is Charisma (spell save DC 13). It can innately cast the following spells, requiring no material components:
  • Magic Resistance. The bean-fionn has advantage on saving throws against spells and other magical effects.
  • Treasure Sense. The bean-fionn can pinpoint, by scent, the location of precious metals and stones, such as coins and gems, within 60 feet of it.
  • Undead Nature. The bean-fionn doesn’t require air, food, drink, or sleep.


  • Multiattack. The bean-fionn makes two attacks with its Claws.
  • Claws. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 6 (1d6 + 3) slashing damage. f the target is Medium or smaller, it is grappled (escape DC 13) and pulled 5 feet toward the bean-fionn. Until this grapple ends, the target is restrained, the bean-fionn tries to drown it, and the bean-fionn can’t use its claws on another target.
  • Healing Kiss (3/Day). The bean-fionn kisses a willing creature. The target magically regains 11 (2d8 + 2) hit points. In addition, the touch removes all diseases and neutralizes all poisons afflicting the target.
  • Illusory Appearance. The bean-fionn covers herself and anything she is wearing or carrying with a magical illusion that makes her look like a normal human woman. The illusion ends if the bean-fionn takes a bonus action to end it or if she dies. The changes wrought by this effect fail to hold up to physical inspection. For example, the bean-fionn could appear to have smooth skin, but someone touching her would feel her rough flesh. Otherwise, a creature must take an action to visually inspect the illusion and succeed on a DC 20 Intelligence (Investigation) check to discern that the bean-fionn is disguised.


The bean-fionn is an undead creature with an alluring presence. When not using its illusory appearance, it appears as an angry woman in a flowing white gown, reminiscent of the “woman in white” legends. Its eyes shimmer with an otherworldly light, and its hair seems to be composed of cascading water droplets.

The bean-fionn (ban-FIN) resides beneath lakes, rivers, and streams, often in areas with tragic histories. It is particularly active during times associated with transition between seasons.

The bean-fionn is known for its vigilance against those who harm or abuse children. It often lurks near bodies of water, watching for potential victims. When provoked, it can use its claws to pull the offender underwater and deliver a swift retribution.

A child kissed by a bean-fionn is cured of all sickness and harm. This blessing is highly valued among communities that know of the bean-fionn’s existence.
