Amphibious. The aboleth can breathe air and water.

Mucous Cloud. While underwater, the aboleth is surrounded by a transformative mucus. A creature that touches the aboleth or 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 1 hour. The diseases creature can breathe only underwater.

Probing Telepath. If a creature communicates telepathically with the aboleth, the aboleth learns the creature’s greatest desires if the aboleth can see the creature.


Multiattack. The aboleth makes three tentacle attacks.

Tentacle. Melee Weapon Attack. +7 to hit, reach 5 ft., one target. Hit: 11 (2d6+4) 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 only be removed 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.
