ACTIONS
Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 11 (2d6 + 4) piercing damage, and the target is grappled (escape DC 15). If the shroud ray has advantage against the target, the shroud ray attaches to the target’s head, and the target is blinded and suffocating . Until this grapple ends, the shroud ray automatically hits the grappled creature with this attack. When the shroud ray is dealt damage while grappling, it takes half the damage (rounded down) and the other half is dealt to the grappled target. The shroud ray can have only one creature grappled at once.
Tail. Melee Weapon Attack: +7 to hit, reach 10 ft., one creature. Hit: 7 (1d6 + 4) slashing damage plus 3 (1d6) poison damage, and the creature makes a DC 13 Constitution saving throw . On a failure, it is poisoned until the end of the shroud ray’s next turn.
Moan. Each non-aberration creature within 60 feet that can hear its moan makes a DC 13 Wisdom saving throw . On a failure, it is frightened until the end of the shroud ray’s next turn. When a creature succeeds on this saving throw, it becomes immune to the shroud ray’s moan for 24 hours.
Phantasms (1/Day). The shroud ray magically creates flickering illusions of itself in its space. Attacks on it have disadvantage . This effect ends after 1 minute, when the shroud ray enters an area of bright light, or when it successfully grapples a creature.
REACTIONS
Reactive Tail. When hit or missed with a melee attack, the shroud ray makes a tail attack against the attacker.
Angry Moan. When the shroud ray takes damage, it uses Moan.
Combat
A shroud ray never attacks unless it can do so with surprise. It either masquerades as a cloth item or uses Phantasms and lurks in the darkness or overhead. When it attacks, it bites. The first time it is attacked each turn, it uses Reactive Tail or Angry Moan. The shroud ray flees if reduced to 20 hit points or fewer, if a creature escapes its grapple , or when in bright light. While fleeing, it uses its reactions to slow pursuit. A shroud ray forced to flee often returns to stalk its foes, waiting for an opportune time to strike again.

Aberrations are unnatural beings that don’t belong to this plane of existence. Many aberrations are telepathic and use a mental power known as psionic power instead of magic. An aboleth is an aberration.
