:bi:`Amphibious`. The aboleth can breathe air and water.

:bi:`Mucous Cloud`. While underwater, the aboleth is surrounded by
transformative mucus. A creature that touches the aboleth or that hits
it with a melee attack while within 5 feet of it must make a DC 14
Constitution saving throw. On a failure, the creature is diseased for
1d4 hours. The diseased creature can breathe only underwater.

:bi:`Probing Telepathy`. If a creature communicates telepathically with
the aboleth, the aboleth learns the creature's greatest desires if the
aboleth can see the creature.


Actions
^^^^^^^

:bi:`Multiattack`. The aboleth makes three tentacle attacks.

:bi:`Tentacle`. *Melee Weapon Attack:* +9 to hit, reach 10 ft., one
target. *Hit:* 12 (2d6 + 5) bludgeoning damage. If the target is a
creature, it must succeed on a DC 14 Constitution saving throw or become
diseased. The disease has no effect for 1 minute and can be removed by
any magic that cures disease. After 1 minute, the diseased creature's
skin becomes translucent and slimy, the creature can't regain hit points
unless it is underwater, and the disease can be removed only by *heal*
or another disease-curing spell of 6th level or higher. When the
creature is outside a body of water, it takes 6 (1d12) acid damage every
10 minutes unless moisture is applied to the skin before 10 minutes have
passed.

:bi:`Tail`. *Melee Weapon Attack:* +9 to hit, reach 10 ft. one target.
*Hit:* 15 (3d6 + 5) bludgeoning damage.

   single: charmed; by Aboleth Enslave

:bi:`Enslave (3/Day)`. The aboleth targets one creature it can see
within 30 feet of it. The target must succeed on a DC 14 Wisdom saving
throw or be magically :ref:`charmed` by the aboleth until the aboleth dies or
until it is on a different plane of existence from the target. The
:ref:`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.

Whenever the :ref:`charmed` target takes damage, the target can repeat the
saving throw. On a success, the effect ends. No more than once every 24
hours, the target can also repeat the saving throw when it is at least 1
mile away from the aboleth.

Legendary Actions
^^^^^^^^^^^^^^^^^

The aboleth can take 3 legendary actions, choosing from the options
below. Only one legendary action option can be used at a time and only
at the end of another creature's turn. The aboleth regains spent
legendary actions at the start of its turn.

**Detect**. The aboleth makes a Wisdom (Perception) check.

**Tail Swipe**. The aboleth makes one tail attack.

   single: charmed; by Aboleth Psychic Drain

**Psychic Drain (Costs 2 Actions)**. One creature :ref:`charmed` by the aboleth
takes 10 (3d6) psychic damage, and the aboleth regains hit points equal
to the damage the creature takes.
