Illithid Dragon - AI-generated fantasy Monster

Illithid Dragon

An illithid dragon is the result of a forbidden experiment intended to create a perfect servant for the elder brains. The process does not merely graft tentacles onto a dragon. It rewrites instinct, memory, and identity until the creature can coordinate armies through thought alone. Most attempts fail, producing brain-dead monsters or violently unstable aberrations. The rare survivor becomes a sovereign threat capable of turning whole communities into extensions of its mind.

Amphibious. The dragon can breathe air and water.
Magic Resistance. The dragon has advantage on saving throws against spells and other magical effects.
Legendary Resistance. The dragon has three legendary resistances. If it fails a saving throw, it can choose to succeed instead.
Cerebral Grapple. A creature grappled by the dragon is restrained. At the start of each of the dragon's turns, the grappled creature takes 10 () psychic damage as the dragon invades its thoughts.
Draconic Telepathy. The dragon can communicate telepathically with any creature within 120 feet that has a language. The creature does not need to share a language with the dragon to understand its thoughts.
Extract Brain. If a creature fails a saving throw against the dragon's Tentacle attack by 5 or more, the dragon can attempt to extract its brain. The target must succeed on a Constitution saving throw or take 55 () psychic damage. If this reduces the target to 0 hit points, the dragon kills it and consumes its brain.
Psychic Veil. The dragon can use a bonus action to magically become invisible until the start of its next turn. This invisibility ends immediately after the dragon makes an attack or uses a breath weapon.
Aura of Alien Thought. The dragon's presence fractures the minds of lesser creatures. A creature that starts its turn within 30 feet of the dragon and can hear its telepathy must succeed on a Wisdom saving throw or have disadvantage on its next attack roll or saving throw before the start of its next turn.
Multiattack. The dragon makes one Bite attack and two Tentacle attacks.
Bite. Melee Weapon Attack: to hit, reach 10 ft., one target. Hit: 18 () piercing damage plus 7 () psychic damage. If the target is a creature, the dragon can grapple it, escape . Until the grapple ends, the target is restrained, and the dragon cannot use its Bite against another target.
Tentacle. Melee Weapon Attack: to hit, reach 15 ft., one creature. Hit: 11 () bludgeoning damage plus 10 () psychic damage. If the target is a Large or smaller creature, it must succeed on a Intelligence saving throw or be stunned until the end of the dragon's next turn.
Mindfire Breath. The dragon exhales a storm of violet psychic fire in a 60-foot cone. Each creature in that area must make a Dexterity saving throw, taking 49 () psychic damage plus 22 () force damage on a failed save, or half as much damage on a successful one. A creature that fails the save by 5 or more is also frightened of the dragon until the end of its next turn.
Mind Flayer's Gaze. The dragon targets one creature it can see within 120 feet. The target must make a Intelligence saving throw. On a failed save, the target takes 27 () psychic damage and is incapacitated until the end of the dragon's next turn. On a successful save, it takes half as much damage and suffers no other effect. The dragon can then move the target up to 20 feet in any direction, without provoking opportunity attacks.
Psychic Command. The dragon chooses up to three creatures it can see within 120 feet. Each target must make a Intelligence saving throw. On a failed save, a target takes 22 () psychic damage and is charmed by the dragon until the end of the dragon's next turn. While charmed in this way, a target must use its reaction, if available, to make one weapon attack against a creature of the dragon's choice.
Psionic Deflection. When the dragon is hit by an attack, it adds 4 to its AC against that attack, potentially causing it to miss. The dragon must see the attacker and cannot use this reaction while incapacitated.
Tentacle Attack. The dragon makes one Tentacle attack.
Psychic Glide. The dragon moves up to half its speed without provoking opportunity attacks. Each creature within 5 feet of the dragon at any point during this movement must succeed on a Intelligence saving throw or take 7 () psychic damage.
Neural Terror (Costs 2 Actions). One creature the dragon can see within 60 feet must succeed on a Wisdom saving throw or become frightened until the end of its next turn.
