  • Detect Life. The brinemaiden can magically sense the presence of creatures up to 5 miles away that aren’t undead or constructs. She knows the general direction they’re in but not exact locations.
  • Incorporeal Movement. The brinemaiden 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.


  • Corrupting Touch. Melee Spell Attack: +4 to hit, reach 5 ft., one target. Hit: 12 (3d6 + 2) necrotic damage.
  • Calls of the Lost. Each creature within 60 feet of the brinemaiden must succeed on a DC 13 Wisdom saving throw. On a failed save, they must use all of their movement and must take the dash action to move directly toward and into the nearest body of water, as the haunting wails of the drowned call out to them. The creature may take no other actions, bonus actions, or reactions. The target may repeat the saving throw at the end of their turn. A creature who reaches the water while under these effects swims (or walks, if they cannot swim) their full speed directly away from the shore until the effect ends. If there is no water nearby, the creature spends their turn wracked with mournful sobs.
  • Wail (1/Day). The banshee releases a mournful wail, provided that she isn’t in sunlight. This wail has no effect on constructs and undead. All other creatures within 30 feet of her that can hear her must make a DC 13 Constitution saving throw. On a failure, the creature drops to 0 hit points. On a success, a creature takes 10 (3d6) psychic damage.


A ghostly figure of an elven woman floats toward you through the water, its empty eye sockets fixed on yours, its mouth open impossibly wide in an unearthly wail.

Cousin to banshees and drowned maidens, the brinemaiden is the lost spirit of an elven woman who drowned. She floats along coastlines and even through submerged ruins, retracing steps she took often in life. A brinemaiden is an angry and frightened spirit, lashing out at any nearby living creature in her confusion.

Bound to Baubles. A brinemaiden need not be confined to the place of her death and may be bound instead to an item from her life. A trinket, a piece of jewelry, or even the last thing she saw as she drowned can be the tether for her rage-filled soul. Many brinemaidens are bound to bits of sea glass, as the shattered remnants of stained-glass windows filled the swirling waters around them as they drowned.

Undead Nature. A brinemaiden doesn’t require air, food, drink, or sleep.
