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.

Black Cloud (Ex): Up to three times per day an achaierai can release a choking, toxic black cloud. Those other than achaierai within 10 feet instantly take 2d6 points of damage. They must also succeed at a Fortitude save (DC 15) or be affected for 3 hours as though by an insanity spell cast by a 16th-level sorcerer.

Babble (Su): An allip constantly mutters and whines to itself, creating a hypnotic effect. All sane creatures within 60 feet of the allip must succeed at a Will save (DC 16) or be affected as though by a hypnotism spell for 2d4 rounds. This is a sonic, mind-affecting compulsion. Opponents who successfully save cannot be affected by the same allip's babble for one day.

Wisdom Drain (Su): Those whose Wisdom is reduced to 0 by the allip become helpless until at least 1 point of Wisdom is restored.

Madness (Su): Anyone targeting the allip with a mind-control or telepathic ability makes direct contact with its tortured mind and takes 1d4 points of temporary Wisdom damage.

Improved Grab (Ex): To use this ability, the ankheg must hit with its bite attack. If it gets a hold, it deals automatic bite damage each round the hold is maintained. If the ankheg is damaged after grabbing its prey, it retreats backward down its tunnel at burrowing speed, dragging the victim with it.

Acid (Ex): Acidic enzymes drip from an ankheg's mouth each round it maintains a hold. It automatically deals 1d4 points of acid damage each round in addition to bite damage.

Spit Acid (Ex): Stream of acid 5 feet high, 5 feet wide, and 30 feet long, once every 6 hours; damage 4d4, Reflex half DC 14. One such attack depletes the ankheg's acid supply for 6 hours. It cannot spit acid or deal acid damage during this time. Ankhegs do not use this ability unless they are desperate or frustrated. They most often spit acid when reduced to fewer than half their hit points or when they have not successfully grabbed an opponent.

Tremorsense (Ex): Ankhegs can automatically sense the location of anything within 60 feet that is in contact with the ground.

Spells: Araneas cast spells as 3rd-level sorcerers (save DC 12 + spell level). They prefer illusions and charms but avoid fire spells.

Web (Ex): In spider or hybrid form (see Alternate Form, below), an aranea can cast a web up to six times per day. This is similar to an attack with a net but has a maximum range of 50 feet, with a range increment of 10 feet, and is effective against targets of up to Large size. The web anchors the target in place, allowing no movement. An entangled creature can escape with a successful Escape Artist check (DC 20) or burst the web with a successful Strength check (DC 26). The web has 6 hit points and takes double damage from fire.

Poison (Ex): Bite, Fortitude save (DC 13); initial damage 1d6 temporary Strength, secondary damage 2d6 temporary Strength.

Alternate Form (Su): An aranea's natural form is that of a Large monstrous spider. It can assume two other forms. The first is a Small or Medium-size humanoid (the exact form is fixed at birth). The second form is a Medium-size, spider-humanoid hybrid. Changing form is a standard action. In humanoid form, the aranea gains all the abilities of the form (for example, an aranea in dwarf form has dwarven racial traits). The aranea keeps its ability scores and can cast spells, but it cannot use webs or poison in humanoid form. In hybrid form, an aranea looks like a humanoid at first glance, but a successful Spot check (DC 18) reveals the creature's fangs and spinnerets. The aranea can use weapons and webs in this form. An aranea remains in one form until it chooses to assume a new one. A change in form cannot be dispelled, nor does the aranea revert to its natural form when killed. A true seeing spell, however, reveals its natural form if it is in humanoid or hybrid form.

Entangle (Su): An assassin vine can animate plants within 30 feet of itself as a free action. The effect lasts until the vine dies or decides to end it (also a free action). The ability is otherwise similar to entangle as cast by a 4th-level druid (save DC 13).

Improved Grab (Ex): To use this ability, the assassin vine must hit with its slam attack.

Constrict (Ex): An assassin vine deals 1d6+7 points of damage with a successful grapple check against Medium-size or smaller creatures.

Blindsight (Ex): Assassin vines have no visual organs but can ascertain all foes within 30 feet using sound, scent, and vibration.

Camouflage (Ex): Since an assassin vine looks like a normal plant when at rest, it takes a successful Spot check (DC 20) to notice it before it attacks. Anyone with Wilderness Lore or Knowledge (plants or herbs) can use those skills instead of Spot to notice the plant. Dwarves can use stonecunning to notice the subterranean version.

Poison (Ex): Bite, Fortitude save (DC 22); initial damage 1d6 temporary Strength, secondary damage 2d6 temporary Strength.

Heat (Ex): Azers' bodies are intensely hot, so their unarmed attacks deal additional fire damage. Their metallic weapons also conduct this heat.

Construct: Immune to mind-influencing effects, poison, disease, and similar effects. Not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage.

Blind (Ex): A sheetlike animated object such as a carpet or tapestry can grapple an opponent up to three sizes larger. The object makes a normal grapple check. If it gets a hold, it wraps itself around the opponent's head, blinding that creature until removed. The blinded creature cannot make Spot, Search, or Track checks and suffers a -6 circumstance penalty to other checks related to perception, such as Listen.

Constrict (Ex): A flexible animated object such as a rope, vine, or rug deals automatic slam damage with a successful grapple check against creatures up to one size larger than itself. An object of at least Large size can make constrict attacks against multiple creatures at once, if they all are at least two sizes smaller than the object and fit under it.

Trample (Ex): An animated object of at least Large size and with a hardness of at least 10 can trample creatures two or more sizes smaller for the object's slam damage. Opponents who do not make attacks of opportunity against the object can attempt Reflex saves (DC 10 + 1/2 object's HD) to halve the damage.

Hardness (Ex): An animated object has the same hardness it had before it was animated.

Improved Speed (Ex): The base speeds given in the statistics block assume that animated objects lurch, rock, or slither along. Objects with two legs (statues, ladders) or a similar shape that allows faster movement have a speed bonus of 10 feet. Objects with multiple legs (tables, chairs) have a speed bonus of 20 feet. Wheeled objects gain a speed bonus of 40 feet. Objects might have additional modes of movement. A wooden object can float and has a swim speed equal to half its land speed. A rope or similar sinuous object has a climb speed equal to half its land speed. A sheetlike object can fly (clumsy maneuverability) at half its normal speed.

Construct: Immune to mind-influencing effects, poison, disease, and similar effects. Not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage.
