Gray Glutton
A gray glutton is a magically mutated hulking creature with a rough, warty hide. It runs on all four limbs, but rears up on its legs to attack with its sharp claws. Needlelike teeth fill its maw.
Magically Created. Gray gluttons were created by transforming another creature through dark magic rituals, stripping it of its intellect. It is believed that the transformed creatures bore a grudge against psychics and accepted magical mutation as they share a single-minded hatred for any creature that taps psychic energy.
Psychic Hater. A gray glutton know no fear, desiring only to tear psionic creatures apart. It willingly dives into combat even against numerous foes when it detects psychically able creatures. It will also attack nonpsionic creatures as well, but will attack a psychic before any other target, switching and moving to that target the moment it uses a psychic ability or spends ki or power points.

Hostile Mind. When the gray glutton is the target of telepathy power or a spell or feature that targets its mind, such as telepathy, the creature targeting the gray glutton must succeed on a DC 16 Charisma saving throw or take 7 (2d6) psychic damage.
Psionic Hole. Whenever a creature hits the gray glutton with a melee attack, it loses concentration unless it succeeds on a DC 15 Constitution saving throw. A creature which succeeds on the save is immune to this effect for 1 minute.
Psionic Resistance. The gray glutton has advantage on saving throws against psionics and other psychic effects.
Actions
Multiattack. The gray glutton makes two attacks: one with its bite and one with its claws.
Bite. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 17 (2d8 + 8) piercing damage.
Claws. Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 22 (4d6 + 8) slashing damage.
Nullifying Exhalation (Recharge 6). The gray glutton exhales poisonous gas in a 15 foot cone. Each creature within that area must make a DC 15 Constitution saving throw. On a failed save, the target takes 20 (8d4) poison damage and loses 5 (2d4) power or ki points (power points lost first). On a successful save, the target only takes half of the damage.
