The Shattered Eulogy of Lost Merfolk

In the depths of sunken ruins and along forlorn beaches, a haunting presence stirs. A phantasmal manifestation of grief and despair, this creature embodies the lost voices of merfolk who perished seeking vengeance against those who wronged them. Ethereal and shimmering, it glides through the water with an eerie grace, its split visage forever mourning the tragic fate of its kin. Glowing with bioluminescent hues, the creature captures the attention of unwary adventurers, luring them into an otherworldly lament that can drain the very essence of joy from hearts. Those caught in its sorrowful serenade find themselves compelled to witness the tragic tales of the drowned, their minds and souls at risk of being eternally claimed.

Special Traits

Ethereal Beauty. As a bonus action, the creature can choose one creature it can see within 60 feet of it. That creature must succeed on a DC 15 Wisdom saving throw or be charmed by this creature until the end of its next turn. While charmed in this way, the target is incapacitated and loses the ability to take reactions.

Lamenting Echoes. When a creature that the monster can see makes a successful attack roll against the monster, the attacker must succeed on a DC 15 Constitution saving throw or take 14 (4d6) psychic damage as the cries of lost merfolk surge through their mind and sap their resolve.

Unheard Resentment (Recharge 5-6). The creature unleashes a haunting wail that echoes through the waters. Each creature within a 30-foot radius must make a DC 17 Wisdom saving throw or take 27 (6d8) psychic damage and be frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Actions

Multiattack. The creature makes two Soul Riptide attacks.

Soul Riptide. Melee Spell Attack: +8 to hit, reach 15 ft., one target. Hit: 22 (4d10) necrotic damage. The target must make a DC 15 Constitution saving throw or have its hit point maximum reduced by an amount equal to the necrotic damage taken. This reduction lasts until the creature finishes a long rest.

Nightmare Serenade (Recharge 4-6). The creature sings a melodious yet mournful tune. Each creature of its choice within 60 feet that can hear it must succeed on a DC 18 Wisdom saving throw or be incapacitated until the end of its next turn. While incapacitated, creatures are unable to willingly move away from a space within 30 feet of the monster.
