Body Thief (Su)

As a full-round action that provokes an attack of opportunity, an intellect devourer can reduce its size, crawl into the mouth of a helpless or dead humanoid, and burrow into the victim’s skull to devour its brain. This is a coup de grace attempt. If the victim is slain (or already dead), the intellect devourer usurps control of the body and may use it as its own, as if it controlled the target via a dominate person spell. The intellect devourer has full access to all of the host’s defensive and offensive abilities save for spellcasting and spelllike abilities (although the 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 spells or effects that preserve corpses). As long as the intellect devourer occupies the body, it knows (and can speak) the languages known by the victim and basic information about the victim’s identity and personality yet has none of the victim’s specific memories or knowledge. Damage done to a host body does not harm the intellect devourer, and if the host body is slain, the intellect devourer emerges and is dazed for 1 round. Only a 5th-level or higher mystic cure can restore the victim of body theft. Once per day as a standard action, an intellect devourer can unerringly teleport onto the head of a helpless or dead creature it can see within 100 feet.

Id Stimulation (Su)

Once per minute as a standard action, an intellect devourer can overstimulate the pleasure and pain receptors of a creature within 100 feet. The target is Stunned”>stunned for 1d4+1 rounds; a successful DC 18 Will save reduces the duration to 1 round. This is a mind-affecting effect.

Vulnerability to Good-Aligned Weapons (Ex)

Weapons with a good alignment bypass an intellect devourer’s damage reduction and deal an additional 50% damage.


Environment any underground
Organization solitary, brood (2–6), or tribe (7–16)

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 living 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.
