Phantom of the Churning Abyss
In the depths of tumultuous waters or dark swamps, a ghostly figure weaves through the mists, shrouded in a cloak of shadow and energy. This ethereal being appears as a distorted visage of despair, with swirling blue and green luminescence emanating from its form. Its eyes glow like radiant specters, evoking a sense of dread and curiosity in those who encounter it. The creature is known to lure hapless adventurers into its grasp, driven by a hunger for their life essence. When engaged in battle, it floats above the ground, twisting and turning like a whirlpool, leaving behind faint trails of shifting shades. Its presence distorts reality, warping time and space around it, making it a uniquely fearsome foe.

Unique Trait: Abyssal Distortion. When a creature starts its turn within 30 feet of this being, it must succeed on a DC 15 Wisdom saving throw or become disoriented. If disoriented, a creature rolls one less die on its attack rolls until the start of its next turn.
Actions
Multiattack. The creature makes two attacks: one with its Tethering Grasp and one with its Abyssal Bolt.
Tethering Grasp. Melee Spell Attack: +8 to hit, reach 10 ft., one creature. Hit: 22 (4d10) necrotic damage, and the target's speed is reduced to 0 until the end of its next turn. If the target is a humanoid, it must succeed on a DC 15 Constitution saving throw or be paralyzed until the end of its next turn.
Abyssal Bolt. Ranged Spell Attack: +8 to hit, range 120 ft., one target. Hit: 18 (4d8) necrotic damage. The target must succeed on a DC 15 Constitution saving throw or have its hit point maximum reduced by an amount equal to the necrotic damage taken until the target finishes a long rest.
Rejuvenating Mists (Recharge 5-6). The creature releases a cloud of ethereal mist in a 20-foot radius. Each creature within the area must succeed on a DC 15 Constitution saving throw or take 27 (6d8) necrotic damage and be blinded until the end of its next turn. On a successful save, the creature takes half damage and is not blinded. The creature heals for half the total damage dealt by this ability.
Legendary Actions

- Shift in Shadows. The creature teleports up to 30 feet to an unoccupied space it can see.
