Brainstealer dragon

A brainstealer dragon was a hybrid of illithid and dragon, combining the best, or worst, features of both.

Description
Like most illithids and their creations, brainstealer dragons had four lengthy tentacles in place of their heads. Above and behind these, they possessed two white bloated and lidless orbs in place of eyes. Their draconic bodies were covered in small pale purple scales and their wings were reduced to fleshy flaps of skin.

Personality
Brainstealers possessed the conniving personalities and manipulative minds of their mind flayer creators. Most saw life as a game, and one they planned to win. To advance their schemes, they would use and influence the minds of underworld denizens. A few great wyrm brainstealers even had whole illithid communities under their control. They were more skilled in deception, intelligence gathering, and survival than their normal dragon counterparts.

Abilities
The brainstealer's powerful draconic build was aided by its diverse array of mental abilities. Like their illithid kin, they could use a mind blast to mentally debilitate their prey. This replaced a dragon's breath weapon, and got longer and stronger as the brainstealer aged, and they were immune to such powers used against them. They retained a dragon's aura of fear.

Depending on their stage of development, brainstealers above the age of wyrmling had all conventional illithid psionics, being capable of making suggestions, levitation, charming their enemies, detecting thoughts, projecting their minds into the Astral Plane, and shifting between planes (in either magical or psionic forms). Moreover, they were capable of telepathic communication to any language-using creature up to away. Like dragons, they could learn to cast spells as sorcerers, or manifest psionic powers as telepaths.

Their skin was immune to acid, and grew in resistance to non-magical means of attack as they grew older. The downside to their transformation was that their "wings" were far less powerful, and so their flight was clumsy and more difficult.

Tactics
At the start of a fight, brainstealer dragons typically used their mind blasts to stun their prey for ease of consumption. They then grabbed them with their tentacles and commenced brain extraction, a process that took about 30 seconds, and usually killed their victims.

Unlike regular dragons, brainstealers could not bite or use their wings as weapons, but they could still use their dragon's claws with which to fight. While their tentacles were comparatively weak, they were long and capable of grabbing victims.

Homes
They were found underground.

History
Their origin was unknown, but obvious: scholars of the underworld believed brainstealers to be the product of an illithid breeding program, and likely one that not even their elder brains could control.
