The aboleth can breathe air and water.
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.
If a creature the aboleth can see communicates telepathically with the aboleth, the aboleth learns the creature's greatest desires.
The aboleth makes two Tentacle attacks.
Melee Attack Roll: +9 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) bludgeoning damage plus 3 (1d6) psychic damage.
