Genetic Recall (Ex)

Due to the genetic memory passed from parent to child, an aboleth is always considered trained when making a skill check.

Mucus Cloud (Ex)

While underwater or in microgravity, an aboleth exudes a cloud of transparent slime. All creatures adjacent to an aboleth in such conditions must make a DC 19 Fortitude save or lose the ability to breathe air while gaining the ability to breathe water for the next three hours. Renewed contact with the cloud requires another save, with each failure extending the duration for three hours. Sealed environmental suits prevent the need to make a save.

Slime (Ex)

A creature hit by an aboleth’s tentacle while not fully sealed in an environmental suit must make a DC 20 Fortitude save or have their flesh transform into a clear, slimy membrane over the course of the next four rounds. This new flesh is soft and tender, reducing the victim’s Constitution by 4 as long as it persists. If not moistened at least once an hour, the victim’s flesh will dry out, inflicting 1d10 damage every 10 minutes. Remove affliction and similar effects can restore a creature to normal; immunity from disease offers no protection against this attack.


Environment any aquatic
Organization solitary, small group (1-4)

As befits their hideous primeval appearance, the hermaphroditic aboleths are among the world’s oldest forms of life. Ancient even when the gods first turned their eyes to the Material Plane, the aboleths have always existed apart from other mortal life, alien and cold and endlessly plotting.

They once ruled many worlds with vast empires, and today view most other forms of life as either food or slaves—and sometimes both. They disdain the gods and see themselves as the true masters of creation. An aboleth is 25 feet long and weighs 6,500 pounds.

In the darkest reaches of ocean planets, aboleths still dwell in grotesque cities built in nauseating and cyclopean styles using hybrids of magic and technology. There they are served by countless slaves culled from every nation, air-breathing and aquatic alike, although the air-breathing slaves are doubly bound by magic and the need to constantly replenish their water-breathing ability via the excretions of their aboleth masters. Lone aboleths are often advance scouts for these hidden cities, seeking out new slaves. When a planet’s resources decline, aboleth elder brain-pools merge their consciousness to seek out new realms for conquest through the Dimension of Dreams, using their magitech to unleash world-shattering cataclysms to devastate planets they leave behind.
