An aboleth attacks by flailing with its long, slimy tentacles,
though it prefers to fight from a distance using its illusion
Transformation (Ex): A blow from an aboleth's tentacle
can cause a terrible transformation. Affected creatures must
succeed at a Fortitude save (DC 19) or begin to transform over
the next 1d4+1 minutes, the skin gradually becoming a clear,
slimy membrane. A transformed creature must remain moistened with
cool, fresh water or suffer 1d12 points of damage every 10
minutes. 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 change.
Psionics (Sp): At will: hypnotic pattern, illusory wall,
mirage arcana, persistent image, programmed image, project image,
and veil. These effects are as the spells cast by a 16th-level
sorcerer (save DCs, where applicable, are 13 + spell level).
Enslave (Su): Three times a day, an aboleth can attempt to
enslave any one living creature within 30 feet. The target must
succeed at a Will save (DC 17) or be affected as though by a
dominate person spell cast by a 16th-level sorcerer. An enslaved
creature obeys the aboleth's telepathic commands (but will
not fight on its behalf) until freed by remove curse or dispel
magic, 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 one mile from its slave.
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
at a Fortitude save (DC 19) or lose the ability to breathe air
for the next 3 hours. The 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.
