Magic Resistance. Qunbraxel has advantage on saving throws against spells and other magical effects.

Spellcasting (Psionics). Qunbraxel casts one of the following spells, requiring no spell components and using Charisma as the spellcasting ability (spell save DC 16):

At will: detect magic, detect thoughts, levitate, mage armor (self only), mage hand (the hand is invisible), prestidigitation

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

2/day each: confusion, sending, telekinesis

Multiattack. Qunbraxel makes two Eldritch Bolt attacks, or one Eldritch Bolt attack and one Tentacle attack.

Tentacle. Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit:15 (2d10 + 4) psychic damage. If the target is Medium or smaller, it has the grappled condition (escape DC 16) and must succeed on a DC 16 Intelligence saving throw or have the stunned condition until the grapple ends.

Eldritch Bolt. Ranged Spell Attack: +8 to hit, range 120 ft., one target. Hit:20 (3d10 + 4) force damage.

Extract Brain. Melee Weapon Attack: +8 to hit, reach 5 ft., one Humanoid with the stunned condition who is grappled by Qunbraxel. Hit:55 (10d10) piercing damage. If this damage reduces the target to 0 hit points, Qunbraxel kills it by extracting and devouring its brain.

Mind Blast (Recharge 5–6). Qunbraxel magically emits psychic energy in a 60-foot cone. Each creature in that area must succeed on a DC 16 Intelligence saving throw or take 26 (5d8 + 4) psychic damage and have the stunned condition for 1 minute. A stunned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
