Chaosfell Wraith

Displacement. The Chaosfell Wraith projects a magical illusion that makes it appear to be standing near its actual location, causing attack rolls against it to have disadvantage. If it is hit by an attack, this trait is disrupted until the end of its next turn. 

Avoidance. If the Chaosfell Wraith is subjected to an effect that allows it to make a saving throw to take only half damage, it instead takes no damage if it succeeds on the save and half damage if it fails.

Incorporeal Movement. The Chaosfell Wraith can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Flyby. The Wraith doesn't provoke opportunity attacks when it flies out of an enemy's reach.

Keen Hearing and Smell. The Wraith has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Siphoning Nature.  When the wraith deals damage towards a target it will siphon the target lifeforce healing half of the total damage dealt.

 Multiattack.The wraith can do two attacks either two Eldridge claw attacks or a psionic sickle attack.

Eldritch Claw. Melee Attack Roll: +11, reach 5 ft. Hit: 18 (2d8 + 9) Slashing damage plus 9 (2d8) Psychic damage.

Psionic Sickle. Melee attack roll: +11, reach 10ft. Hit:  27 (6d8) Psychic Damage. The target must make a Dexterity saving throw of DC 18 or be restrained on a failed save and not restrained on a success. (Max of two targets, one for each sickle arm.)

Spellcasting. The Wraith casts one of the following spells, requiring no Material components and using Charisma as the spellcasting ability (spell save DC 19, +11 to hit with spell attacks):

At Will.  Chaos bolt (psychic)4th level, ray of sickness, poison spray 5th level

3 times per day: Semantic Snap, Tasha Mind whip, Phantasmal force. 5th level

1 time per day:  Phantasmal killer, Psychic Scream 9th level

Veil of chaos (recharge 5-6). The wraith unleashes a twisted melody that provides it and its allies a boost as the Wraith gains a +3 to its AC and gains 50 temporary hp and has an 20ft aura around it. Any ally of the wraith within the 20ft radius gains +2 to AC, advantage on attack rolls, and adds 1d8 Psychic damage to their damage rolls. (The ability ends when the temporary hp is depleted.)

Sorrowful Cry. The Wraith chooses a target (max of 3 targets) to inflict a debilitating cry. Each creature afflicted must make a Wisdom saving throw DC 18, on a failed save the target gains an aura with a radius of 15ft if the target and its allies are within the zone they receive disadvantage on attack rolls, saving throws, gains a -3 to AC, and gains Vulnerability to Psychic Damage. The target can reroll the save at the end of their turn.

Twisted double. As a bonus action the Wraith uses its chaos infused magic to split itself into two other duplicate versions of itself; the duplicate shares the same initiative as the original. (The clones have the same stats as the original but have differences. They do not have sorrowful cry or veil of chaos, they cannot use spell slots, they have 1 hp, and do half the total damage of the original for example instead of 2d8 they do 1d8, and 3d8 instead of 6d8,) After this move is performed the wraith and it duplicates gain invisibility until the end of it next turn.

Chaotic warp. As a bonus action the wraith teleports to an unoccupied space within 60ft as it reappears in that space any creature within 10ft of the wraith appearing takes 2d12 force damage and is knocked back 10ft.

Preemptive Strike. As a reaction the wraith can use one Eldridge claw attack towards its attacker with advantage.
