Amygdala, The Mind's Eye

Creature Sense. The Mind's Eye is aware of the presence of creatures within 5 miles of it that have an Intelligence score of 4 or higher. It knows the distance and direction to each creature, as well as each one’s Intelligence score, but can’t sense anything else about it. A creature protected by a mind blank spell, a nondetection spell, or similar magic can’t be perceived in this manner.

Innate Spellcasting (Psionics). The Mind's Eye’s innate spellcasting ability is Intelligence (spell save DC 17). It can innately cast the following spells, requiring no components:

At will: detect thoughts, levitate

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

Legendary Resistance (3/Day). If the Mind's Eye fails a saving throw, it can choose to succeed instead.

Telepathic Hub. The Mind's Eye can use its telepathy to initiate and maintain telepathic conversations with up to ten creatures at a time. The Mind's Eye can let those creatures telepathically hear each other while connected in this way.

Tentacle. Melee Weapon Attack: +7 to hit, reach 30 ft., one target. Hit: 20 (4d8 + 2) bludgeoning damage. If the target is a Large or smaller creature, it is grappled (escape DC 15) and takes 9 (1d8 + 5) psychic damage at the start of each of its turns until the grapple ends. The Mind's Eye can have up to four targets grappled at a time.

Mind Blast (Recharge 5–6). The Mind's Eye magically emits psychic energy. Creatures of the Mind's Eye’s choice within 60 feet of it must succeed on a DC 17 Intelligence saving throw or take 32 (5d10 + 5) psychic damage and be stunned for 1 minute. A target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Psychic Link. The Mind's Eye targets one incapacitated creature it can perceive with its Creature Sense trait and establishes a psychic link with that creature. Until the psychic link ends, the Mind's Eye can perceive everything the target senses. The target becomes aware that something is linked to its mind once it is no longer incapacitated, and the Mind's Eye can terminate the link at any time (no action required). The target can use an action on its turn to attempt to break the psychic link, doing so with a successful DC 17 Charisma saving throw. On a successful save, the target takes 10 (3d6) psychic damage. The psychic link also ends if the target and the Mind's Eye are more than 5 miles apart, with no consequences to the target. The Mind's Eye can form psychic links with up to ten creatures at a time.

Eye Rays. The Mind's Eye shoots three of the following magical eye rays at random (reroll duplicates), choosing one to three targets it can see within 120 feet of it:

1. Charm Ray. The targeted creature must succeed on a DC 16 Wisdom saving throw or be charmed by the Mind's Eye for 1 hour, or until the Mind's Eye harms the creature. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

2. Paralyzing Ray. The targeted creature must succeed on a DC 16 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

3. Fear Ray. The targeted creature must succeed on a DC 16 Wisdom saving throw or be frightened for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

4. Enervation Ray. The targeted creature must make a DC 16 Constitution saving throw, taking 36 (8d8) necrotic damage on a failed save, or half as much damage on a successful one.

5. Telekinetic Ray. If the target is a creature, it must succeed on a DC 16 Strength saving throw or the Mind's Eye moves it up to 30 feet in any direction. It is restrained by the ray’s telekinetic grip until the start of the Mind's Eye’s next turn or until the Mind's Eye is incapacitated.

If the target is an object weighing 300 pounds or less that isn’t being worn or carried, it is moved up to 30 feet in any direction. The Mind's Eye can also exert fine control on objects with this ray, such as manipulating a simple tool or opening a door or a container.

6. Disintegration Ray. If the target is a creature, it must succeed on a DC 16 Dexterity saving throw or take 45 (10d8) force damage. If this damage reduces the creature to 0 hit points, its body becomes a pile of fine gray dust.

If the target is a Large or smaller nonmagical object or creation of magical force, it is disintegrated without a saving throw. If the target is a Huge or larger object or creation of magical force, this ray disintegrates a 10-foot cube of it.

Sense Thoughts. The Mind's Eye targets a creature with which it has a psychic link. The Mind's Eye gains insight into the target’s reasoning, its emotional state, and thoughts that loom large in its mind (including things the target worries about, loves, or hates). The Mind's Eye can also make a Charisma (Deception) check with advantage to deceive the target’s mind into thinking it believes one idea or feels a particular emotion. The target contests this attempt with a Wisdom (Insight) check. If the Mind's Eye succeeds, the mind believes the deception for 1 hour or until evidence of the lie is presented to the target.

Antimagic Cone (Recharge 5–6). When attacked or targeted with a spell, the Mind's Eye's central eye creates an area of antimagic, as in the antimagic field spell, in a 120-foot-cone until the end of its next turn. The area works against the Mind's Eye's own eye rays, but not it's psionic abilities.

Spell Reflection. If the Mind's Eye makes a successful saving throw against a spell, or a spell attack misses it, the Mind's Eye can choose another creature (including the spellcaster) it can see within 30 feet of it. The spell targets the chosen creature instead of the Mind's Eye. If the spell forced a saving throw, the chosen creature makes its own save. If the spell was an attack, the attack roll is rerolled against the chosen creature.

The Mind's Eye can take 3 legendary actions, choosing from the options below. It can take only one legendary action at a time, can only use each action only once per round, and only at the end of another creature’s turn. The Mind's Eye regains spent legendary actions at the start of its turn.

Tentacle. The Mind's Eye makes a tentacle attack.

Eye Ray. The Mind's Eye uses one random eye ray.

Break Concentration. The Mind's Eye targets a creature within 120 feet of it. If the target fails a DC 17 Wisdom save, the Mind's Eye breaks the creature’s concentration on a spell it has cast. The saving throw is at disadvantage if the Mind's Eye has a psychic link with the target. The creature also takes 1d4 psychic damage per level of the spell on a failed save, or half as much damage on a successful one.

Psychic Pulse. The Mind's Eye targets a creature within 120 feet of it with which it has a psychic link. Enemies of the Mind's Eye within 10 feet of that creature take 10 (3d6) psychic damage.

Sever Psychic Link. The Mind's Eye targets a creature within 120 feet of it with which it has a psychic link. The Mind's Eye ends the link, causing the creature to have disadvantage on their next ability check, attack roll, and saving throw until the end of the creature’s next turn.
