Arcane Master - The Illusionist

Master of Illusions. When the Illusionist is subjected to an illusion spell he automatically succeeds on the saving throw and regains 13 (3d8) hit points. Additionally, his own illusions keep him alert. He cannot be surprised and senses magic within 120 feet of him at will.

Legendary Resistance (3/Day). If the Illusionist fails a saving throw, he can choose to succeed instead.

Displacement Form. Attack rolls against the Illusionist are made with disadvantage unless the Illusionist is incapacitated.

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

Shielded Mind. the Illusionist is immune to scrying and to any effect that would sense his emotions, read his thoughts, or detect his location.

Ventriloquism. Whenever the Illusionist speaks, he can choose a point within 120 feet; his voice emanates from that point

Multiattack. Illusionist makes two Mind-Shattering Bolt attacks or exchanges one of them for a use of his Monstrous Illusions, if available. Mind-Shattering Bolt. Ranged Spell Attack: +11 to hit, range 120 ft., one target. Hit: 29 (4d10 + 7) psychic damage, and the target must succeed on a DC 15 Constitution saving throw or be stunned until the end of its next turn.

Monstrous Illusions (Recharge 5-6). The Illusionist can magically force a creature he can see within 120 feet of him to make a DC 19 Constitution saving throw. Unless the saving throw is a success, the creature is surrounded by tangible illusions of flesh-tearing monstrosities, as if encased in a field of magical energy. While encased in this way, the creature is incapacitated, has a speed of 0, and takes 13 (3d8) psychic damage at the start of each of its turns and before repeating the saving throw (save ends.)

Spellcasting. The Illusionist's spellcasting ability is Intelligence (spell save DC ). The Illusionist has the following spells prepared:

At will: illusory script, mage hand, minor illusion, mirror image

4/day each: Hallucinatory Terrain, hypnotic pattern, Phantasmal Killer

3/day each: detect thoughts, dimension door, major image, mislead, Shield, telekinesis

2/day each: delayed blast fireball, programmed illusion, seeming, teleport

1/day each: feeblemind, mirage arcane, project image

The Illusionist 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 Illusionist regains spent legendary actions at the start of his turn.

Illusive Dash. The Illusionist moves up to his speed in three seemingly different directions at once. If a creature hits or misses one of these projections with an opportunity attack during this move, it creates an illusion paradox and the attacker takes 19 (3d8) force damage.

Unraveling of Arcana (Costs 2 Actions). The Illusionist targets one creature he can see within 60 feet of himself. The target must succeed on a DC 19 Constitution saving throw or take 35 (10d6) force damage, and each spell of 5th level or lower on the target ends.

Masterful Illusions (Costs 3 Actions; 3/Day). The Illusionist casts the major image spell four times, targeting different areas with it. The Illusionist prefers to create images of his foes' worst fears (if he knows them) or of void-warped entities that are unfathomable to a mortal's mind. The Illusionist doesn't need to concentrate on the spells, which cease at the end of his next turn. Each creature that can see these illusions must succeed on a DC 19 Wisdom saving throw or become frightened of the illusion for 1 minute (save ends at end of turn for each frightened creature).
