 ***Multiattack.*** The morkoth makes three attacks: two with its bite and one with its tentacles or three with its bite.
***Bite.** Melee Weapon Attack:* +6 to hit, reach 5 ft., one target. *Hit:* 9 (2d6 + 2) slashing damage.
***Tentacles.** Melee Weapon Attack:* +6 to hit, reach 15 ft., one target. *Hit:* 15 (3d8 + 2) bludgeoning damage, and the target is grappled (escape DC 14) if it is a Large or smaller creature. Until this grapple ends. the target is restrained and takes 15 (3d8 + 2) bludgeoning damage at the start of each of the morkoth's turns. and the morkoth can't use its tentacles on another target.
 On initiative count 20 (losing initiative ties), the morkoth takes a lair action to cause one of the effects described below:
* The morkoth uses its Hypnosis action, originating at a point within 120 feet of itself. It doesn't need to see the effect's point of origin.
 The island surrounding a morkoth's lair is warped by the creature's presence, creating the following effects:
* The morkoth is aware of any new arrival, whether an object or a creature, on its island or in its sanctum. As an action, the morkoth can locate any one creature or object on the island. Visitors to the island feel as though they are being watched, even when they aren't.
* Each time a creature that has been on the island for less than a year finishes a short or long rest, it must make a DC 10 Intelligence (Investigation) check. On a failure, the creature has misplaced one possession (chosen by the player, if the creature is that player's character). The possession remains nearby but concealed for a short time, so it can be recovered with a successful DC 15 Wisdom (Perception) check. An object that is misplaced but not recovered ends up in the morkoth's lair 1 hour later. If the creature later goes to the morkoth's lair, its lost possessions stand out in its perception and are easily recovered.
* Entrances to the morkoth's lair have an enchantment that the morkoth can activate or suppress at any time while it's in its lair and not incapacitated. Any creature within 30 feet of such an entrance and able to see it must make a DC 15 Wisdom saving throw. On a failed save, the creature feels an intense urge to use its movement on each of its turns to enter the lair and to move toward the morkoth's location (the target doesn't realize it's heading toward a creature). The target moves toward the morkoth by the most direct route. As soon as it can see the morkoth, the target can repeat the saving throw, ending the effect on itself on a success. It can also repeat the saving throw at the end of each of its turns and every time it takes damage.
* With a thought (no action required), the morkoth can initiate a change in the water within its lair that takes effect 1 minute later. The water can be as breathable and clear as air, or it can be normal water (ranging in clarity from murky to clear).

If the morkoth dies, these regional effects end immediately.
