Mind flayer

The **mind flayer**, also called the **illithid**, is an evil and sadistic being, humanoid in appearance, but with a four-tentacled octopus-like head. These beings are feared throughout the Underdark for their telepathic abilities and usually are not without two or more slaves, mentally bound, to each individual mind flayer. Although they cooperate to achieve a goal, they will back away at the first sign that it is not something that will be self-profitable.

They are capable of speaking Undercommon, but prefer telepathic communication and will attempt to mentally dominate any non-slave, non-illithid they meet. Some theorized mind flayers to be aliens from the future (as stated in The Sargmne Prophecies), who had come back in time to save their species from extinction. Another tale is that they are cursed inbred mutant offspring of humans from a distant world. However, more convincing evidence points to a more sinister origin in the Far Realm. They feed on the brains of sentient creatures and are thus feared. Their natural psionic abilities also make them respected in the eyes of the drow, beholders, duergar, and the other dominant races of the Underdark.

## Ecology

### Illithid Psionics

The mind flayers are feared by all beings in the Underdark because of their great mental prowess. Every illithid has a small array of mind-affecting spells to take control of their prey as well as a powerful mind blast to affect a multitude of foes. The mind flayer's mind blast is a 60-foot (20m) cone that stuns anyone caught within it. The mind flayer can also innately cast three mind-affecting spells: charm monster, detect thoughts, and suggestion. Mind flayers are also capable of casting levitate and plane shift.

Normally, a mind flayer will use its mind blast ability to stun a few foes and then drag them away to feed. Once it has its victims, it will attach all of its tentacles to the head of its victim. Then, the mind flayer uses its extract ability to suck out the brains of its victims, instantly killing the victim, as long as it only has one head. The mind flayer uses its other spells mainly to enslave its minions and keep them under total control, as well as on the battlefield.

### Illithid Sorcerers

Although most mind flayer arcanists are wizards, few are also born with gift of sorcery. Because a mind flayer sorcerer is naturally more intelligent than other mind flayers, it is better able to resist psionics. For the most part, an illithid with the gift of sorcery will use defensive spells such as greater invisibility and resist energy as well as spells to further hinder enemies, such as ray of exhaustion and touch of idiocy. A mind flayer who decides to follow the path of wizardry can become an undead creature known as an alhoon lich or an illithilich.

### Society

Mind flayer communities range in size from two hundred to two thousand, and that is counting only the illithids. Each mind flayer in the community likely has at least two slaves to do its bidding. In these communities, the number of slaves often far outstrips the number of mind flayers. For example, the illithid city of Oryndoll has a total population of 26,000, but mind flayers only account for 3,450 of that number.

#### Religion

Mind flayer religion was once non-existent. In the time when they had invaded the shield dwarf kingdom of Shanatar and captured many shield dwarves, there were no gods to the mind flayers. Originally, their plan was to create a superior race of dwarves, skilled in both mechanics and psionics that would be loyal solely to the mind flayers. However, when the dwarves began to stage uprisings and rebellions, the city of Oryndoll, where the experimentation was occurring, was plunged into chaos. The only reason the city did not fall in the duergar rebellions was because of the sudden appearance of the mind flayer god Ilsensine. Since Ilsensine's appearance, the mind flayers have become deeply religious and begun to develop the formidable psionic powers that the race now has. llsensine’s favored proxy is Lugribossk.

Mind flayers once had an additional god called Maanzecorian who was killed by Tenebrous, the undead shadow of the demon lord Orcus, though this fact is unknown to most.
