Aberrations in Pathfinder come from many different sources. The deep sea. Other planets. Other planes. Magic experiments gone horribly wrong. Magic experiments gone horribly right. Or creatures getting exposed to dark energy and mutated by it. Either way, they pose a challenge for Pathfinders.

15. Gibbering Mouther

Aberrations do not make biological sense according to our understanding of biology. No more is this more true than with the Gibbering Mouther. This abomination is a lump of flesh with mouths everywhere. New mouths can appear at will or whenever it’s slashed.

Slashing the Mouther lets them sprout a new mouth and make an attack against the player. Their gibbering can also cause confusion for a round. Furthermore, the creature can spit acid and inflict the dazzled status. 

Gibbering Mouthers can manipulate the terrain around them. Anywhere it moves becomes rough terrain for the duration of the combat. It can also potentially engulf and suffocate players. However, it’s weak to bludgeoning so take advantage of that.

• Ground Manipulation  (occult, transmutation) The gibbering mouther causes stone and earth under its body to grow soft and muddy, remaining so for 1 minute after the mouther moves off the location. A gibbering mouther can move through these areas with ease, but other creatures treat them as difficult terrain.

14. Angoyang

People like cats, Just look at the entirety of the Internet. Some aberrations take advantage of this.

The Angoyang is a cat-like aberration that uses its appearance to full effect. It creates an illusion to make itself look like a cat and hide its more aberrant features. Falling for the illusion makes the character fascinated.

Angoyangs can do damage with their tentacles and can also grab people. If a person is dependent on spells that require reflex saves, this may be a problem as Angoyangs have high reflex saves. Its silent yowl can do severe damage and cause fright.

If the angoyang attacks the creature, the creature can attempt a new save at the beginning of their next turn.

13. Hound of Tindalos

Sometimes, Pathfinders get caught up in time travel shenanigans. However, the various powers that be do not like people mucking about with the time stream. Anyone who crosses that line will be met by the Hounds of Tindalos.

These time-traveling dogs will chase time-travelers anywhere and anywhen they go. They attack in packs. If they gaze at a player, the player may take damage. They’re also tough physical attackers.

They have some interesting quirks. They lose some of their power in curved spaces (any space at a 90-degree angle or more). They also have buff spells like haste. The dogs aren’t subtle at all and prefer a direct confrontation. And the hounds will keep coming.  How the players deal with the hounds long-term depends on the story. But most often, it means setting things right with the powers that be by undoing the effects of their time travel. This will often have tragic consequences.

Hound of Tindalos Stats

• Level 7
• Perception +17; greater darkvision
• Languages Aklo
• Skills Acrobatics +17, Athletics +15, Occultism +17, Stealth +17, Survival +13 (+17 to Track)

• HP 90; Immunities controlled, emotion; Resistances mental 10, poison 10, physical 10

• Ripping Gaze (aura, evocation, occult, visual) 30 feet. The hound of Tindalos's eyes glow balefully, causing painful but bloodless wounds to rip open in the body of a creature that meets its awful gaze. When a creature ends its turn in the aura's emanation, it takes 4d6 slashing damage (DC 25 basic Fortitude save). A creature that critically succeeds at its save is temporarily immune for 24 hours.
• Vulnerable to Curved Space When a hound of Tindalos is not adjacent to a structural angle of 90º (or more acute), its resistance to physical damage is suppressed and it becomes sickened 1. It can't recover from this sickened condition, but the condition ends automatically once the hound is again adjacent to a suitable angle.

• Angled Entry  The hound of Tindalos casts a 4th-level dimension door spell, but it must transport itself into a space adjacent to an angle of 90º (or more acute) in the structure or environment around it. For example, it could teleport to a space adjacent to a wall (using the angle between the wall and floor) or a corner in a room, or adjacent to a sizable tree growing straight up out of the ground, but not to a flat plain or a room with only curved corners and edges.
• Once per day, the hound can use this ability to plane shift to or from the Dimension of Time, with the same restrictions on what angles it can appear next to.

12. Amalgamite

Teleportation is complicated. While spells like dimension door are common, they can and will go wrong if a caster is too arrogant or foolish to calculate properly. When that happens, you get an Amalgamite,

Amalgamites can make everyone around them feel displaced and sickened. Anyone who gets this affliction can spread it easily. They will sometimes destabilize their allied to spread the sickness.

The Amalgamites have another defensive ability. If attacked, they can trade places with a displaced creature. It is entirely possible that a party can hurt themselves this way. Watch out for the warp mind spell too. It can cause permanent confusion.

• Destabilizing Field (aura, conjuration) 40 feet. A creature that begins its turn within the area feels its body begin to stretch and must succeed at a DC 33 Fortitude save or become destabilized. A destabilized creature emits a 10-foot destabilizing field aura and becomes sickened 1. The destabilization ends when the creature is no longer sickened. A creature that succeeds at its saving throw against the aura is temporarily immune to all destabilizing fields for 1 minute.

• Reposition  (concentrate, conjuration, occult, teleportation) The amalgamite teleports into an unoccupied space it can see within 50 feet.
• Transpose  (conjuration, occult, teleportation) The amalgamite chooses up to two destabilized creatures they can see within 50 feet and swaps their positions, or moves a single such creature to an unoccupied space they can see within range. If the amalgamite chooses two creatures, they can choose their self as one of these creatures, but both targets must be the same size. An unwilling creature can attempt a DC 33 Will save. If either target succeeds at this saving throw, both are unaffected.

11. Brain Collector

This scorpion-like entity hails from deep space. It’s part of a group of invaders called the Dominion of the Black. The brain collector has one goal: Collect brains.

To do this, they kill people and store their brains in little pods on their bodies. Their methods of killing vary. They can attack with melee and inject poison that can inflict stupefy. They can also use magic.

This magic can include phantasmal killer While this spell is not strong as it was in 1st edition, it can still be pootentially deadly. If you attack a brain collector and do 30 mental damage or do 25 damage on a critical attack, you can destroy one of the brain pods.

10. Children of Mhar

Aberrations sometimes come to Golarian from deep in the cosmos. Children of Mhar are the children of the aforementioned Great Old One. Though they are children, they can give Pathfinders a run for their money.

These multi-tentacled creatures are powerful fighters whatever strategy they’re using. They can grab Pathfinders and take a bite out of them. They can also use a multi-attack to strike three opponents. They also have strong defenses. They can resist physical damage and can deflect enchantment spells.

On the ranged end, it can shoot balls of lava. It can also create earthquakes that do severe damage and render terrain difficult. Flying won’t help because the creature can use earthbind and make it so creatures can’t fly. They can also spew toxic smog that renders players vulnerable to hallucination spells.

Children of Mhar Stats

• Level 18
• Perception +30; greater darkvision, smoke vision
• Languages Aklo; telepathy 100 feet
• Skills Athletics +37
• Str +9, Dex +6, Con +8, Int -1, Wis +0, Cha +4

Any creature that ends its turn within 30 feet of the deghuun during this time takes 6d6 fire damage and is sickened 1 (DC 38 Fortitude save; the creature avoids the sickened condition on a critical success, or is sickened 2 on a critical failure). While sickened in this way, a creature takes a –2 status penalty to its saving throw against the deghuun's hallucination. Any creature that's in the smog is concealed and treats other creatures as concealed. Strong winds dissipate the smog.
• Tentacle Assault  The deghuun makes three tentacle Strikes, each against a different creature within reach. These attacks count toward its multiple attack penalty as normal.

9. Choker

If you’re doing an aberration-based campaign, a Choker is a good low-level monster to start with. These small creatures from parts unknown, are curious about our society. Unfortunately, it chooses to explore this curiosity by strangling people and stealing their stuff.

Chokers are low-level monsters but they can still be a threat. Getting hit by them allows them to instantly start strangling players. They can also reposition the players they are strangling if they are attacked.

Chokers can use hidden movement to attack any creature that doesn’t detect it. If Chokers feel outnumbered, it will run away, using its ability to squeeze into tight spaces to its advantage. If the party is seeking an object a Choker has stolen, this can be a good chase sequence.

Choker Stats:

• Level 2
• Perception +7; darkvision
• Languages Aklo, Undercommon
• Skills Athletics +9 (+11 to Grapple), Stealth +9
• Str +3, Dex +3, Con +1, Int -3, Wis +1, Cha -2
• AC 18; Fort +7, Ref +10, Will +7
• HP 28
• Yank  (manipulate) Trigger An enemy targets the choker with an attack; Effect The choker tries to pull a creature it has grabbed or restrained into the path of the attack. The choker attempts an Athletics check, including its bonus to Grapple. If it succeeds against the grabbed or restrained creature's Fortitude DC, the choker redirects the attack to that creature, and the attacker compares its attack roll result against the new target's AC.
• The choker must move the creature into a space adjacent to itself. The creature must also be moved within the attacker's reach against a melee attack or into a space between itself and the attacker against a ranged attack. The choker can't use this ability to make the attacker target itself, even if it's grabbing or restraining the attacker.
• Speed 20 feet, climb 15 feet
• Melee  arm +11 [+6/+1] (reach 10 feet), Damage 1d6+3 bludgeoning plus strangling fingers
• Constrict  1d6+3 bludgeoning, DC 19
• Hidden Movement If the choker starts its turn hidden from or undetected by a creature, that creature is flat-footed against the choker's attacks until the end of the turn.
• Strangling Fingers Any creature hit by a choker's arm Strike is automatically grabbed, and the choker begins to strangle the target. The creature is suffocating and can't speak as long as it's strangled. This prevents it from casting spells with a verbal component or activating items with a command component.

8. Dark Naga

Nagas like money and treasure. They’re willing to kill to get it. Even the basic Dark Naga has enough power to do a lot of damage,

The Dark Naga has powerful fangs that do significant damage. The fangs inject strong venom that can render a player unconscious for multiple minutes, taking them out of the fight. A particularly brutal GM can have the nagas attack the unconscious player.

What can make the Dark Naga brutal is its magic. It can cast wall of fire and lightning brutal. Invisibility gives them the chance to sneak up on the party and inject its venom into a character with low fortitude.

7. Dread Wisp

An angry spirit related to the Will-o’-Wisp. They cause and feed on fear. And more importantly, they’re hard to hit.

They can go invisible at will without limit. They’ll reappear to attack and then disappear again. If dealing with multiple, wisps, this can become a battle of attrition.

Unfortunately for players, using area-of-effect magic to bypass invisibility will not work. So they’ll have to find a way to bypass the invisibility using glitterdust.or some other method. They will need to figure out a way to see too. The dread wisps can switch locations with Shadow Flitter.

Dread Wisp Stats:

• Level 8
• Perception +20; darkvision

• Go Dark  (concentrate) The dread wisp extinguishes their Dread Flickering, becoming invisible. They can end this effect with another use of this action. If the dread wisp uses their draining touch Strike while invisible, the arc of pale energy lets any observer determine their location, making them hidden to all observers only until the dread wisp moves.
• Shadow Flitter  (conjuration, occult, teleportation) The dread wisp teleports to a square they can see within 30 feet that isn't in an area of bright light. The dread wisp can't use Shadow Flitter again for 1d4 rounds.
• Wearying Touch If the dread wisp critically hits with their draining touch Strike, the target is drained 1. 

6. Drider

The drow are infamous for using their dark magic to create aberrations. One of these is the Drider. Drow slaves volunteer to be fleshwarped and turned into spider-like monstrosities to serve as guardians for a period of time in exchange for their freedom. However, they usually don’t live long enough to complete that contract,

Like most drow, the Drider are good with a multitude of weapons. It poses a threat in close and long-range combat. The fleshwarpping process gives them access to powerful venom that can enfeeble party members.

The Drider can also shoot webs to slow down or trap party members. The webs can immobilize opponents. This makes a Drider a threat if encountered in groups. A Drider can also use powerful magic including suggestion and fireball.

5. Ghonhatine

When it comes to creating abominations, the drow can be equally innovative and horrifying. In an attempt to recreate an extinct monster, the drow created the Ghonhatine. Whether the creation is faithful to the original is irrelevant. It’s still horrifying.

The Ghonhatine is a physical powerhouse. They can be a problem when paired or when accompanied by other enemies. Their jaws can do additional acid damage.

Their vomit can be used as a ranged attack. They can inflict a disease that can kill a character. However, the big problem is that if a character dies during an encounter with a Ghonhatine, the Ghonhatine will try to eat the dead body, making the character that much harder to resurrect.

Ghonhatine Stats

While within the aura, affected creatures take a –2 circumstance penalty to saves against disease and to recover from the sickened condition. A creature that succeeds at its save is temporarily immune for 1 minute.

4. Intellect Devourer

The Dominion of the Black is always trying to infiltrate societies. Their advance scouts are Intellect Devourers. While some might think that advance scouts are less of a threat, this is a mistake.

Intellect Devourers can steal bodies and possess people. Usually taking their physical abilities and general knowledge in the process. If the creature takes a fighter for example, they will have the abilities of the fighter. Once the body is destroyed, this walking brain will try to possess another body.

The big challenge with this fight is not just dealing with the possessed body, but killing the creature quickly. It will hop from body to body. Each time it does this, it heals completely. And it may keep some underlings in the encounter for spare parts.

At the start of the intellect devourer's next turn, the body revives at its maximum Hit Points, controlled by the devourer. The intellect devourer is conscious and can sense everything the possessed body could. Any effect that ends the possession kills the host body with the same effects as Exit Body. The intellect devourer can't use any of the host creature's spells with Body Thief but can use its own spells. The host body slowly decays while inhabited by the intellect devourer, becoming uninhabitable after 7 days unless preserved with gentle repose or a similar effect.
• Exit Body  (move) Requirements The intellect devourer is controlling a body with Body Thief; Effect The intellect devourer leaves its host body, which dies instantly and is no longer a suitable host for any Body Thief ability. The intellect devourer appears at full size in an adjacent space.
• Ravage  The intellect devourer makes two talon Strikes against a paralyzed, restrained, or unconscious creature, using the same attack modifier as its highest attack modifier. These Strikes gain the death trait. If Ravage kills the target, the intellect devourer may use Body Thief against it as a free action.
• Stolen Identity While an intellect devourer uses Body Thief, it gains the ability to understand and speak all languages known by the host, as well as knowledge of the host body's abilities, identity, role in society, and personality. However, it does not gain the specific memories or knowledge of the host body.

3. Shanrigol Behemoth

A Shanrigol Behemoth is created from a Shanrigol Heap that has grown large enough to become a real threat. While not evil, it seeks to consume anything it sees, And Pathfinders count as anything.

This gargantuan monstrosity has strong defenses. They resist bludgeoning and piercing damage. They fight by grabbing opponents, shredding their flesh, and squeezing the life out of them. Each time the behemoth does this, it regains hit points. The ability to shoot web and immobilize party members is a major threat.

This creature can cause persistent bleed damage. As long as the character is bleeding, they are enfeebled.  This fight is a slugfest but players will want to get clear. When destroyed, it’ll explode in a pile of stench.

2. Veiled Masters

The Veiled Masters covertly controlled the world for eons. Once humans in Azlant started getting wise to the scheme, the Veiled Masters decided to drop a meteor on the situation. Unfortunately for the Veiled Masters, they also got up in the blast. However, they survived and are always plotting ways to reassert control.

The Veiled Masters’ main tactic is to control things from afar, rarely getting their own fins dirty. When they’re forced into direct combat, they’re still powerful. Their physical are brutal. Their slime can inflict the drained status which lowers max HP. Their tentacles can also do electricity damage.

The real threat is the spells. Veiled Masters are masters of illusion and enchantment. They can cast things like dominate and suggestion. They can turn the party against each other quickly.

• Mucus Cloud (aura, disease) 30 feet. While underwater, a veiled master exudes a cloud of transparent slime.

• Occult Rituals DC 37; 5th geas
• Change Shape  (concentrate, occult, polymorph, transmutation) Once per round, a veiled master can take on the appearance of a humanoid of Large, Medium, or Small size or resume its true form. While in humanoid form, the veiled master’s Speed is 30 feet, and it loses its mucus cloud aura and swim Speed. If the humanoid form assumed lacks the aquatic trait, the veiled master loses its own aquatic trait as well. In humanoid form, the veiled master can use weapons, or it can make Strikes that work like its tentacle attack but use the reach of its current form. If the assumed form has fangs or claws, the veiled master can also make such Strikes, but these attacks lack the veiled master’s slime.
• Consume Memories (mental, occult) When a veiled master makes a fangs Strike against a creature, it can consume some of that creature’s memories. The target must succeed at a DC 37 Fortitude saving throw or become stupefied 1. A veiled master regains 5 Hit Points each time it successfully consumes memories. When a veiled master consumes memories, it learns some of the creature’s memories (subject to the GM’s discretion).
• Delayed Suggestion (enchantment, occult) When a veiled master successfully casts dominate on a creature, a suggestion spell triggers when the dominate spell ends. This suggestion usually causes the target to return to the veiled master, so the creature can cast dominate again, but a veiled master can set the suggestion to different orders if it wishes.
• Slime (curse, occult, virulent) Saving Throw Fortitude DC 36; Stage 1 no ill effect (1 round); Stage 2 the victim’s skin softens, inflicting drained 1 (1 round); Stage 3 the victim’s skin transforms into a clear, slimy membrane, inflicting drained 2 until the curse ends; every hour this membrane remains dry, the creature’s drained condition increases by 1 (permanent). A remove disease spell can counteract this curse, but immunity to disease offers no protection against it.
• Tentacle Flurry  The veiled master thrashes about with its tentacles. Make a tentacle Strike against each creature within its reach. Roll only one attack roll, and roll the damage only once for all targets.
• Thoughtlance (curse, enchantment, occult) A creature touched by the veiled master’s tentacles, whether those tentacles deal damage or not, must attempt a DC 34 Will save, becoming slowed 1 on a failure or slowed 2 on a critical failure. Each time the affected creature ends its turn, its slowed value decreases by 1.

1. Worm that Walks

Some wizards don’t care for the whole death concept. If they don’t come to terms with it, they’ll delve into dark magic. Some will become liches. But more creative wizards will take the worms that will consume their corpse and make a body out of them. It’s as horrific as it sounds.

Since they’re powerful wizards, they have powerful spells. Spells like phantasmal killer and warp mind can kill or permanently incapacitate a character. Other spells like dominate create more problems for the party.

For all the trouble these wizards go through to stay alive, they have many defenses to prevent players from putting them in the ground. If a party brings this wizard’s HP to 0, it will discorporate into a swarm and scatter. If one worm survives, it will reform.

Worm that Walks Stats

• Level 14
• Perception +25; darkvision, tremorsense (imprecise) 30 feet
• Languages Aklo, Common
• Skills Acrobatics +24, Deception +28, Intimidation +26, Occultism +27, Society +23, Stealth +28
• Str +5, Dex +8, Con +5, Int +5, Wis +4, Cha +8
• AC 36 all-around vision; Fort +23, Ref +28, Will +26
• HP 200 (fast healing 10); Immunities disease, paralyzed, poison, precision, swarm mind, unconscious; Resistances physical 10; Weaknesses area damage 10, splash damage 10
• Discorporate When the worm that walks is reduced to 0 HP, it discorporates and the component worms that make up its body disperse in every direction. If even a single worm escapes, the worm that walks will eventually re-form using a process that typically takes 1d10 days.
• While the exact circumstances and surroundings determine how long the worm that walks's foes have to dispatch the fleeing worms before they escape, usually its foes have only a single round. Typically, this requires the application of an area effect or splash weapon within 1 round to the space where the worm that walks collapsed. After any amount of area or splash damage is dealt to that space, the character dealing the damage must attempt a DC 15 flat check. Each subsequent area or splash damage effect performed on the area reduces the DC of this flat check by 2, to a minimum of DC 5. If any of these flat checks succeed, none of the worms escape, and the worm that walks is destroyed permanently. At the GM's discretion, clever means of trapping or otherwise detaining the vermin may extend the time allowed to finish off the worm that walks.
• Speed 30 feet
• Melee  tendril +29 [+24/+19] (reach 10 feet), Damage 4d8+14 persistent piercing damage

• Squirming Embrace  The worm that walks Strides, ending its movement sharing a space with a creature, and deals 5d8 piercing damage to the creature. The creature can attempt a DC 32 basic Reflex save.
• Swarm Shape  (concentrate) The worm that walks collapses into a shapeless swarm of worms. It drops all held, worn, and carried items. While discorporated, the worm that walks can't use attack actions and can't cast spells, but it can move through areas small enough for its individual worms to fit without having to Squeeze. It can use the same action to coalesce back into its normal form.
