Veilwhisper Serpent of the Moonlit Abyss

Beneath the obsidian waters of the Moonlit Abyss, a serpentine creature awaits, wrapped in shadows and moonlight. Its long, sinuous body is adorned with scales that shimmer like starlit night, glowing faintly with a silvery hue. The creature's elongated head features hypnotic, pale eyes that seem to draw in the gaze of anyone who meets them. When it swims, the water around it stirs with phantasmal energies, causing illusions to flicker at the edge of perception. This entity uses its innate connection to the moon to manipulate the aquatic environment and ensnare unsuspecting prey within webs of shadow and magic.

Special Traits
Moonlit Veil. As a bonus action, the creature can create a shroud of moonlit shadows in a 30-foot radius around itself. This area is considered difficult terrain, and creatures within it have disadvantage on Wisdom saving throws against being charmed.

Lunar Illusion. When the creature takes damage, it can reroute some of that energy into creating illusory duplicates of itself until the end of its next turn. Each duplicate appears within 10 feet of it, and attackers must roll a d4 to determine whether they hit the real creature or a duplicate. The duplicates vanish if they are struck.

Actions
Multiattack. The creature makes two attacks: one with its Bite and one with its Ensnaring Shadow.

Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 18 (2d10 + 5) piercing damage.

Ensnaring Shadow. Ranged Spell Attack: +6 to hit, range 60 ft., one target. Hit: 22 (4d10) psychic damage, and the target must succeed on a DC 15 Strength saving throw or be grappled. The grappled target takes 7 (2d6) psychic damage at the start of its turn.

Reactions
Slither into Darkness. When targeted by an attack, the creature can use its reaction to become invisible until the start of its next turn. This ability can be used three times per day.
