  • Amphibious. A bog nixie can breathe air and water.
  • Innate Spellcasting. The bog nixie’s spellcasting ability is Charisma (spell save DC 14) and requires no material components for the following spells:
  • Shapechanger. A bog nixie can use her action to polymorph into a Small or Medium aquatic creature, or back into her true form. Her statistics, other than her size, are the same in each form. Any equipment she is wearing or carrying isn’t transformed. She reverts to her true form if she dies.


  • Shortsword. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage.
  • Light Crossbow. Ranged Weapon Attack: +5 to hit, range 80/320 ft., one target. Hit: 7 (1d8 + 3) piercing damage.
  • Lure. A bog nixie sings a magical melody. Every humanoid and giant within 300 feet of her that can hear her song must make a DC 13 Wisdom saving throw or be charmed until the song ends. The bog nixie must use a bonus action on subsequent turns to continue singing. The bog nixie can stop singing at any time. The song ends if the bog nixie is incapacitated. While charmed by the bog nixie, a target is incapacitated and ignores the songs of other bog nixies. If the charmed target is more than five feet away from the bog nixie, the target must move on its turn toward her by the most direct route, trying to get within five feet. It doesn’t avoid opportunity attacks, but before moving into damaging terrain such as lava or a pit, and whenever it takes damage from a source other than the bog nixie, the target can repeat the saving throw. A charmed target can also repeat the saving throw at the end of each of its turns. If the saving throw is successful, the effect ends on it. A target that successful saves is immune to the bog nixie’s song for the next 24 hours.


Nixies are capricious water spirits that dwell in lakes and other large bodies of fresh water. They make their homes in the deeper waters, weaving together lilies and other water plants to form simple yet elegant homes. They are green-skinned with dark green hair and silver eyes, comely in form and feature, and have webbed hands and feet. While not aggressive, they can entrance humanoids and lure them into the water to become servants of the nixies for a year, after which the being is released. During their time in captivity, the captives are given the ability to breath underwater.

Bog nixies are the evil cousins of the nixies that guard ponds, rivers, and lakes. They relish in tricking unsuspecting travelers or hunters into entering dangerous waters where the bog nixie can torment their victim or watch them drown.
