Magic Resistance. Voalsh has advantage on saving throws against spells and other magical effects.
Legendary Resistance (3/Day). If Voalsh fails a saving throw, she can choose to succeed instead.
Innate Spellcasting (Psionics). Voalsh's innate spellcasting ability is Intelligence (spell save DC 15). She can innately cast the following spells, requiring no components:
At will: detect thoughts, detect magic, mage hand (the hand is invisible)
3/day each: dispel magic, clairvoyance
1/day each: dominate monster, plane shift (self only)
Multiattack. Voalsh makes two tentacle or fist attacks.
Tentacles. Melee Weapon Attack: +9 to hit, reach 5 ft., one creature. Hit: 21 (3d10 + 5) psychic damage. If the target is Medium or smaller, it is grappled (escape DC 17) and must succeed on a DC 17 Intelligence saving throw or be stunned until this grapple ends.
Fist. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 5) bludgeoning damage.
Extract Brain. Melee Weapon Attack: +9 to hit, reach 5 ft., one incapacitated humanoid grappled by Voalsh. Hit: The target takes 55 (10d10) piercing damage. If this damage reduces the target to 0 hit points, Voalsh kills the target by extracting and devouring its brain.
Mind Blast (Recharge 5–6). Voalsh magically emits psychic energy in a 60-foot cone. Each creature in that area must succeed on a DC 15 Intelligence saving throw or take 22 (4d8 + 4) psychic damage and be stunned for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Unleash Void (Recharge 5–6). Voalsh opens a rift into the Far Realm, centered on a point Voalsh can see within 60 feet of herself, and a tentacle lashes across creatures near the rift. Each creature other than mind flayers within 30 feet of the rift must make a DC 17 Intelligence saving throw, after which the tentacle disappears and the rift closes. On a failed save, a creature takes 18 (4d8) cold damage from the rift plus 18 (4d8) psychic damage from the tentacle and has the stunned condition for 1 minute. On a successful save, a creature takes half as much damage only. A stunned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Warp Reality. When hit by an attack roll, Voalsh gains a +4 bonus to her AC against that attack roll, potentially causing it to miss. Then Voalsh, along with any equipment she is wearing or carrying, magically teleports up to 60 feet to an unoccupied space she can see.
Description
The three most ruthless, domineering, and cunning mind flayers in Illithinoch spent their early lives scheming against one another. A few decades ago, they each realized the potential in working together and swiftly dominated Illithinoch's other mind flayers. Once they became masters of the stronghold, these three mind flayers engaged in increasingly bizarre and esoteric rituals with the weakened elder brain.
The three mind flayers eventually heard a strange psychic call from a Far Realm godlet called Ilvaash, the Dissonant Psyche. Singing a siren song made up of profane and alien whispers, Ilvaash invited the three mind flayers to join the godlet's psyche—much like mind flayers normally join a hive mind—and leave behind any reliance on Illithinoch's diseased elder brain. Ilvaash also promised the three mind flayers vast power, but only if they would carry Ilvaash's worship into their world. The mind flayer fanatics agreed, embracing their new Far Realm godlet and in turn adopting new personalities that set them apart from their ilk.
The three fanatics are Chishinix, Hashutu, and Voalsh. Each considers themself the group's leader and Ilvaash's secret favorite. Although most mind flayers reject the notion of having individual personalities, the fanatics have embraced their own unique qualities, each hoping to become Ilvaash's most beloved.
In a desperate bid to reclaim their autonomy, the other mind flayers of Illithinoch ambushed Voalsh. Right before the moment of her death, Ilvaash granted her wings, which unfurled from her back like enormous, writhing tentacles. Voalsh vanquished her foes from above in short order. Ever since, she regularly takes to the air to investigate her paranoid suspicions that her enemies might attack at any time. Voalsh has fashioned a magical, floating disk that she often uses to hover above the eye level of anyone else, unfurling her wings to emphasize her intimidating and otherworldly nature.
