Actions

Gatling Mind. The telepath uses mind bullets three times.   Mind Bullets. Melee Weapon Attack: +7 To Hit ( 1d20+7 ), Range 120 ft, One Creature. Hit: 9 ( 1d10+4 ) psychic damage.   Tentacles. Melee Weapon Attack: +7 To Hit ( 1d20+7 ), Reach 10 ft, One Creature. Hit: 15 ( 2d10+4 ) psychic damage. If the target is Large or smaller, it is grappled (Escape DC 15) and must succeed on a DC 15 Intelligence saving throw or be stunned until this grapple ends.   Extract Brain. Melee Weapon Attack: +7 To Hit ( 1d20+7 ), reach 5ft, One Incapacitated humanoid grappled by the telepath. Hit: 55 (10D10) piercing damage. If this damage reduces the target to 0 hit points, the telepath kills the target by extracting and devouring its brain. This grants the telepath another use of its Legendary Resistance trait.   Mind Blast (Timer 1d4). The telepath psionically manifests 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.   Enslave (3/Day). The telepath targets one creature it can see within 30 feet of it. The target must succeed on a DC 15 Wisdom saving throw or be magically charmed by the telepath until the telepath dies or until it is on a different plane of existence from the target. The charmed target is under the telepath's control and can't take reactions, and the telepath and the target can communicate telepathically with each other over any distance. Whenever the charmed target takes damage, the target can repeat the saving throw. On a success, the effect ends. No more than once every 24 hours, the target can also repeat the saving throw when it is at least 1 mile away from the telepath. This enslavement also affects intelligent constructs (such as robots and androids) where it is permanent as the telepath rewrites the robot's code. The construct can be restored if re-programmed again.

Reactions

Telekinetic Shield. As a reaction to an attack hitting the telepath, an invisible barrier of magical force appears and protects you. Until the start of your next turn, you have a +5 bonus to AC, including against the triggering attack, and you take no damage from magic missile.

Legendary Actions

The telepath can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The telepath regains spent legendary actions at the start of its turn.

• Manifest. The telepath manifests an available psionic power of its choice.
• Flexible Tactics. The telepath makes one tentacle or mind bullet attack.
• Psychic Drain. One creature charmed by the telepath takes 10 ( 3d6 ) psychic damage, and the telepath regains hit points equal to the damage the creature takes.
