Body Thief (Su)

As a full-round action that provokes an attack of opportunity, a mythic intellect devourer can reduce its size, crawl into the mouth of a helpless or dead creature, and burrow into the victim’s skull to devour its brain. This is a coup de grace attempt that inflicts 8d4+3d6+32 points of damage. If the victim is slain (or already dead), the mythic intellect devourer usurps control of the body and may use it as its own, as if it controlled the target via a dominate monster spell. The mythic intellect devourer has full access to all of the host’s defensive and offensive abilities save for spellcasting and spell-like abilities (although the mythic intellect devourer can still use its own spell-like abilities). A host body may not have been dead for longer than 1 day for this ability to function, and even successfully inhabited bodies decay to uselessness in 7 days (unless this time is extended via gentle repose). As long as the mythic intellect devourer occupies the body, it knows (and can speak) the languages known by the victim, has detailed information about the victim’s identity and personality, and has access to all of the victim’s specific memories and knowledge.

This allows the mythic intellect devourer to make Knowledge skill checks based on its victim’s Knowledge skills, even if the mythic intellect devourer does not have that particular skill. Damage done to a host body does not harm the mythic intellect devourer, and if the host body is slain, the mythic intellect devourer emerges and is staggered for 1 round. Raise dead cannot restore a victim of body theft, but resurrection or more powerful magic can. A mythic intellect devourer can expend one use of mythic power as a swift action to unerringly teleport onto the head of a helpless or dead creature it can see within 100 feet, then using its body thief ability as above.

Extraordinary Agility (Ex)

A mythic intellect devourer can expend one use of mythic power as a swift action to gain evasion and a +8 dodge bonus to AC and on Acrobatics checks until the start of its next turn.

Id Stimulation (Su)

Once per minute, a mythic intellect devourer can expend one use of mythic power to over overstimulate the pleasure and pain receptors of a creature within 100 feet.

The target is stunned (if non-mythic) or staggered (if mythic) for 1d4+1 rounds; a successful DC 18 Will save reduces the duration to 1 round. dazed for 1 round (stunned if a nonmythic creature). This is a mind-affecting effect. The save DC is Charisma-based.

Vulnerable to Protection from Evil (Ex)

An intellect devourer is treated as a summoned creature for the purpose of determining how it is affected by a protection from evil spell.


Environment any underground
Organization solitary, brood (1 mythic intellect devourer and 2–6 intellect devourers), or tribe (1 mythic intellect devourer and 7–17 intellect devourers)
Treasure triple

Devoid of a head, or any features at all save for four short, clawed legs, this creature’s body looks like a large, glistening brain.


Mythic Psionic Intellect Devourer

A mythic psionic intellect devourer has identical statistics in most respects, but gains the psionic subtype, its spell resistance becomes power resistance, and it gains Wild Talent as a bonus feat. In addition, it replaces a standard intellect devourer’s spell-like abilities with the following psi-like abilities:

Psi-Like Abilities (ML 8th; concentration +12)

  • Constant—detect psionics
  • At will— cloud mind (three creatures, DC 19), compression (two size categories), ego whip (2d4, DC 18*), empty mind (+5 on Will saves*), id insinuation (three targets, DC 18*)
  • 3/day—body adjustment (3d12), intellect fortress (2 rounds), painful strike

Thought by some to be invaders from another dimension or planet, the sinister intellect devourers are certainly one of the world’s cruelest races. Incapable of experiencing emotions or wallowing in the sins of physical pleasure on their own, intellect devourers are forced to steal bodies in order to indulge their gluttony, lust, and cruelty. Stories tell of entire cities of these creatures deep underground, where host bodies are worn like clothes to hideous orgies and vile feasts. Lone intellect devourers often dwell in ruins or caves on the edge of a civilized region so they can make periodic forays into town to “shop” for an attractive new body.

An intellect devourer is 3 feet long and weighs about 60 pounds.
