A creation of the mind flayers, a brain golem exists entirely to fulfill their desires.

A brain golem appears as a burly humanoid, about 8 feet call and 5 feet wide, with an oversized brain serving as its entire head. In fact, the whole body is made up of brain tissue that is covered with a thin film of slimy skin.

Brain golems do not speak or understand any language, despite their intelligence, but they respond to telepathic commands from any mind flayer.


Golems are tenacious in combat and prodigiously strong as well. They are emotionless and cannot be provoked, but those described here are inherently cruel and love to torment their foes.

A golem's creator can command it if the golem is within 60 feet and can see and hear its creator. If not under a command, a golem usually follows its last instruction to the best of its ability, though if attacked it returns the attack. The creator can give a golem a simple program to govern its actions in his or her absence, such as "Remain in an area and attack all creatures that enter" (or only a specific type of creature), "Ring a gong and attack," or the like.

Construct Traits: Golems are immune to mind-affecting effects, poison, sleep, paralysis, stunning, disease, death effects, necromantic effects, and any effect that requires a Fortitude save unless it also works on objects. A golem is not subject to critical hits, subdual damage, ability damage, ability drain, energy drain, or death from massive damage.

It cannot heal itself but can be healed through repair. It cannot be raised or resurrected. All golems have darkvision (60-four range).

Brain golems enter combat with a mind blast and then focus their physical attacks on weak-looking opponents. They never attack mind flayers under any circumstances.

Mind Blast (Su): This attack is a 60-foot cone. Anyone caught in this area must succeed on a Will save (DC is) or be stunned for 3d4 rounds. A brain golem can use this ability once per minute.

Inertial Armor (Su): A brain golem's body is surrounded by a tangible field of force similar to that created by the mage armor spell, granting it a +4 armor bonus to Armor Class. Unlike mundane armor, inertial armor carries no armor check penalty, speed reduction, or arcane spell failure chance. Because it is composed of force, incorporeal creatures can't bypass it the way they do normal armor.


The cost given for each golem includes the price of the physical body, plus all the materials and spell components that are consumed during the process or that become a permanent part of the golem.

The first task in the construction of a golem is assembling the golem's physical body. The creator can assemble the body personally or hire someone else to do the job. The builder must have the appropriate skill, which varies with the kind of golem being constructed.

The real work of creating a golem involves extended magical rituals that take two months to complete. Understanding the rituals requires a character of the specified level who has the Craft Magic Arms and Armor and Craft Wondrous Item feats. The creator must labor for at least 8 hours each day in a specially prepared laboratory or workroom. The chamber is similar to an alchemist's laboratory and costs 500 gp to establish.

When not working on the rituals, the creator must rest and can perform no other activities except earing, sleeping, talking. If personally constructing the golem's body, the creator can perform the building and the rituals together. Missing a day of rituals means the process fails and must be started again. Any money spent is lost, but XP are not. The golem's body can be reused, as can the laboratory.

Completing the ritual drains the appropriate XP from the creator and requires casting any needed spells on the final day. The creator must cast the spells personally, but they can come from outside sources, such as scrolls.

A brain golem's body is formed from the brains of intelligent creatures and topped off with a bud from a mind flayer community's elder brain to form the creature's "head." Its skin is a membrane secreted by the elder brain bud.

The golem costs 55,000 gp to create, which includes 1,000 gp for the construction of the body. Assembling the body requires a Heal check (DC 15).

The creator must be 16th level and able to cast arcane spells. Completing the ritual drains 1,200 XP from the creator and requires bull's strength, feeblemind, geas/quest, limited wish, mage armor.
