Special Abilities
Cult Mind (Su) An egregore is created by the combined will of a number of cult members equal to its Hit Dice (minimum 13), and can have a maximum number of members in its cult mind equal to its Hit Dice. Each member must be an intelligent, living creature. These cultists pour their collective psychic consciousness into the collaborative creation of the egregore, granting each member a number of advantages. Creating an egregore involves a ritual lasting 1 day and costing 1,000 gp per Hit Die of the egregore. New creatures can be added to the cult mind only if previous members die or depart (see below). Adding a new member to the cult mind requires a ritual lasting 1 day and costing 1,000 gp. All the other members who are still a part of the cult mind must be present during this ritual or it fails.
As long as a member of the cult mind is within 1 mile of the egregore, the egregore can use any of its spell-like abilities on that member, regardless of the spell's range. If a member of the cult mind is targeted by a mind-affecting spell, the egregore can attempt a Will save as well, and the cult member uses the better of the two results. If the cult member still fails, another member of the cult mind can choose to be affected instead.
In addition, the members of the cult mind share a limited form of telepathy: they are able to send and receive simple messages and emotions, much like the empathic link between a wizard and his familiar.
If a member of the cult mind is slain or travels more than 1 mile from the egregore, its link to the cult mind is severed, and every other member must succeed at a DC 20 Will save or be sickened for 1 round. If the number of members in the cult mind drops below half of the number of Hit Dice possessed by the egregore, the egregore must succeed at a DC 20 Will save or suffer from confusion. The egregore can attempt a new save at the start of each round to regain its senses. As long as the remaining number of members is less than half the egregore's Hit Dice, the egregore must attempt a new save each time a member of its cult mind is slain or leaves the cult mind. If the last member of the cult is slain or leaves the cult mind, the egregore dissipates harmlessly in 1d4 rounds.
Hypnotic Oscillation (Sp) As a standard action, an egregore can weave a hypnotic pattern using its bands of light in a 10-foot radius around itself. Members of its cult mind are immune and don't count towards the spell's Hit Die limit, but otherwise this ability functions as the spell.
Light Tentacles (Su) An egregore produces bands of light powered by its concentrated mental energy. It can cause these bands to become solid and lash out as tentacles. These tentacles follow all the normal rules for tentacles, except that they function as though they had the brilliant energy weapon special ability.
Psychic Conduit (Ex) Any member of a cult mind can channel any psychic spells it casts through the egregore, as long as the cultist is within 30 feet of the egregore. If a cultist casts spells in this way, treat the egregore as if it were the spellcaster for purposes of the spell's range, point of origin, and other functions that depend on the caster's location. The creature casting the spell still provokes any attacks of opportunity or other negative consequences of casting a spell. The egregore takes 1d6 points of slashing damage per level of spell cast through it in this way as the energy cuts its way out of the creature, though its damage reduction applies. (A 0-level spell channeled through the egregore deals no damage to it.)
When an especially powerful psychic leads a community of like-minded individuals, that group can pool its collective will together to create an egregore. The egregore is a powerful defender and a focal point for the psychic talents of every member of the group, granting them access to additional magical powers and a communal link.
Though egregores' appearances vary, they typically have a core that resembles a mass of brains, discernible by practitioners of phrenology as bearing characteristics of the brains of those who make up its cult mind. This core projects an image that reflects the ideals for which the egregore was formed—an unblinking eye to represent vigilance, a heraldic shield for protection, or some other stylized emblem to reflect the goals of the group. From this bizarre hovering mass emerges a number of pulsating arcs of light that move in a strange unison, forming an almost mesmerizing pattern with their cadence.
The synchronized synaptic pulses that emit from the egregore's cranial core manifest as elegant arcs of light leaping from one brain-shape to another in a rhythmic dance. The egregore can divert an arc outward, transforming it into a semi-solid band of light it can use to strike its foes. These bands normally pass through objects, but by concentrating more fully, the egregore can transform an arc into an even more solid form capable of manipulating objects.
Typically, the sort of cult that creates an egregore is formed of a small association of individuals under the guidance of a strong-willed psychic leader, who directs the weaker-minded followers in a ritual that combines their latent psychic energy into the creation of a powerful entity to support the goals of the organization.
The egregore itself is a totally separate creature, akin to the eidolons of summoners, though it seems to be a genuine living being of the Material Plane and not a true outsider. Creating an egregore requires a cult of 13—one leader and a dozen followers. Larger cults are capable of creating more powerful egregores, with stories circulating of doomsday cults with hundreds of members working together to create an abomination, but subsequently losing control and facing annihilation from their own creation. The egregore exists only as long as the cult that created it, fading back into the psychic ether from which it spawned once the cult is no more.
An egregore is 12 feet across, though the bands of light that extend out from it cause it to fluctuate between an effective size of 13 feet to 15 feet. It weighs only 300 pounds despite its vast size. The brains that make up the egregore's body aren't constructed like human brains, and are far less dense; they seem to take the form of brains only because of the conceptual link they represent. Likewise, the egregore's staring eye and bands of light are more metaphorical than physical.
Egregore Master
When a larger cult creates an egregore, it is often considerably more dangerous than standard egregores. Use the following guidelines when creating an egregore master. An egregore master is created by combining the will of a powerful cult leader and his followers. While the minimum number of cultists required for the creation of a normal egregore is 13, the more members willing to surrender to the cult mind and the stronger their belief in the ideals of the leader, the more powerful the resultant being.
Hit Dice: An egregore master always has more Hit Dice than a normal egregore, though after 13 Hit Dice, increasing its Hit Dice by 1 typically requires adding two or more cult members. An egregore master can have a cult of any size (minimum 15).
Challenge Rating: For every 2 Hit Dice over 13 an egregore master possesses, increase its CR by 1.
Size: Once an egregore master reaches 15 Hit Dice, its size increases to Huge; at 20 Hit Dice it becomes Gargantuan, and at 25 or more Hit Dice it becomes Colossal.
Armor Class: An egregore master has a natural armor bonus equal to half its Hit Dice.
Attacks: For every 3 Hit Dice the egregore master possesses beyond 13, it gains one additional light tentacle attack.
Caster Level: An egregore master has a caster level equal to its HD or the caster level of the cult leader, whichever is lower.
Psychic Magic: For every 2 Hit Dice the egregore master possesses above 13, it adds one spell to those it can cast using psychic magic, and its maximum PE increases by an amount equal to the spell's level. An egregore master can choose a spell from any spell list, but it can't choose a spell with a level equal to more than half its Hit Dice. Egregore masters typically choose spells that enhance the powers of their cult minds or protect their members. It is very rare for an egregore master to choose offensive spells.
