Mucous Cloud

While underwater, the aboleth is surrounded by a cloud of sticky mucus. A creature that touches the aboleth or hits it with a melee attack while within 5 feet of it must succeed on a DC 14 Strength saving throw or be restrained until the end of the aboleth's next turn.

Bonus actions

Enslave (Recharge 4–6)

The aboleth targets one creature it can see within 30 feet of itself. The target must succeed on a DC 14 Wisdom saving throw or be magically charmed by the aboleth until the aboleth dies or until it is on a different plane of existence from the target. The charmed target is under the aboleth's control and can't take reactions, and the aboleth and the target can communicate telepathically with each other over any distance.

The charmed target can repeat the saving throw whenever it takes damage, ending the effect on itself on a success. No more than once every 24 hours, the target can repeat the saving throw when it is at least 1 mile away from the aboleth.

Legendary action uses: 3. The creature can use one option at the end of another creature’s turn and regains spent uses at the start of its turn.
