Innate Spellcasting (Psionic). The dragon’s innate spell casting ability is Intelligence (spell save DC 15). It can innately cast the following spells, requiring no components:

At will: detect thoughts, levitate

1/day each: dominate monster, plane shift (self only)

Multiattack. The dragon makes three attacks, two with its claws and one with its tentacles.

Claw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 5) slashing damage.

Tentacles. Melee Weapon Attack: +9 to hit, reach 15 ft., one creature. Hit: 14 (2d10 + 4) psychic damage. If the target is Huge or smaller, it is grappled (escape DC 15) and must succeed on a DC 14 Intelligence saving throw or be stunned until this grapple ends.

Extract Brain. Melee Weapon Attack: +9 to hit, reach 5 ft., one creature. Hit: 40 (8d10) piercing damage. If this damage reduces the target to 0 hit points, the dragon kills the target by extracting and devouring its brain.

Mind Blast (Recharge 5–6). The dragon magically emits psychic energy in a 30-foot cone. Each creature in that area must make a DC 15 Intelligence saving throw or take 54 (10d10 + 4) psychic damage and be stunned for 1 minute. A creature can repeat the saving throw at each of its turns, ending the effect on itself on a success.
