Aboleth

The aboleth is a revolting fishlike amphibian found primarily in subterranean lakes and rivers. It despises all nonaquatic creatures and attempts to destroy them on sight. An aboleth has a pink belly. Four pulsating blue-black orifices line the bottom of its body and secrete gray slime that smells like rancid grease. It uses its tail for propulsion in the water and drags itself along with its tentacles on land. An aboleth weighs about 6,500 pounds. Aboleths are cruel and highly intelligent, making them dangerous predators. They know many ancient and terrible secrets, for they inherit their parents’ knowledge at birth and assimilate the memories of all they consume. Aboleths are smart enough to refrain from immediately attacking land dwellers who draw near. Instead they hang back, hoping their prey will enter the water, which they often make appear cool, clear, and refreshing with their powers of illusion. Aboleths also use their psionic abilities to enslave individuals for use against their own companions. Aboleths have both male and female reproductive organs. They breed in solitude, laying 143 eggs every five years. These eggs grow for another five years before hatching into full-grown aboleths. Although the young are physically mature, they remain with their parent for some ten years, obeying the older creature utterly.

An aboleth attacks by flailing with its long, slimy tentacles, though it prefers to fight from a distance using its illusion powers.

Enslave (Su): Three times per day, an aboleth can attempt to enslave any one living creature within 30 feet. The target must succeed on a DC 17 Will save or be affected as though by a dominate person spell (caster level 16th). An enslaved creature obeys the aboleth’s telepathic commands until freed by remove curse, and can attempt a new Will save every 24 hours to break free. The control is also broken if the aboleth dies or travels more than 1 mile from its slave. The save DC is Charisma-based.

Psionics (Sp): At will—hypnotic pattern (DC 15), illusory wall (DC 17), mirage arcana (DC 18), persistent image (DC 18), programmed image (DC 19), project image (DC 20), veil (DC 19). Effective caster level 16th. The save DCs are Charisma-based.

Slime (Ex): A blow from an aboleth’s tentacle can cause a terrible affliction. A creature hit by a tentacle must succeed on a DC 19 Fortitude save or begin to transform over the next 1d4+1 minutes, the skin gradually becoming a clear, slimy membrane. An afflicted creature must remain moistened with cool, fresh water or take 1d12 points of damage every 10 minutes. The slime reduces the creature’s natural armor bonus by 1 (but never to less than 0). The save DC is Constitution-based.

A remove disease spell cast before the transformation is complete will restore an afflicted creature to normal. Afterward, however, only a heal or mass heal spell can reverse the affliction.

Mucus Cloud (Ex): An aboleth underwater surrounds itself with a viscous cloud of mucus roughly 1 foot thick. Any creature coming into contact with and inhaling this substance must succeed on a DC 19 Fortitude save or lose the ability to breathe air for the next 3 hours. An affected creature suffocates in 2d6 minutes if removed from the water. Renewed contact with the mucus cloud and failing another Fortitude save continues the effect for another 3 hours. The save DC is Constitution-based.

Skills: An aboleth has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.
