Aspect of Abaraxas

Deadly Acceleration. When Abraxas hits with any weapon, the weapon does an extra 22 (4d10) force damage (included in the attack).

Legendary Resistance (5/Day). If Abraxas fails a saving throw, he can choose to succeed instead.

Precongnition. Abraxas is always under the effects of the foresight spell, which cannot be dispelled.

Second Chance. If Abraxas is slain, his body evaporates but his mind refuses to accept its fate, and the instant before death his mind travels back in time to a point one year before his death with all of the knowledge of when and where he dies, so he may avoid what had happened.

Spatial Awareness. Abraxas can sense everything happening on the Material Plane in a 180-foot radius sphere around him even if he is blinded, his vision is obscured or he doesn't have line of sight.

Innate Spellcasting. Aspect of Abraxas's innate spellcating ability is Charisma (spell save DC 24, +16 to hit with spell attacks). Abraxas can cast the following spells, requiring no material components:

At will: magnify gravity (as a 3rd level spell),enlarge/reduce (self only), slow, pulse wave (as a 4th level spell)

Special Equipment. Abraxas carries a magical longsword named Galactic Longsword. It is a +3 longsword.

Temporal Awareness. Abraxas adds his Intelligence modifier to his initiative rolls.

Timeless Nature. Abraxas doesn't require air, food, sleep or drink and does not age. In addition, Abraxas cannot be put to sleep by magical means or be magically aged.

Multiattack. Aspect of Abraxas uses his Telekinesis, or Teleport. He then makes three attacks with his Galactic Longsword.

Galactic Longsword. Melee Weapon Attack: +20 to hit, reach 5 ft., one target. Hit: 20 (2d8 + 11) slashing damage, or 22 (2d10 +11) slashing damage when used two handed, plus 22 (4d10) force damage. He can extend the length of this blade giving it the reach property, if it ever leaves his hand it returns to normal.

Teleport. Abraxas teleports himself, along with any equipment he is wearing or carrying, and any willing target that he is touching, to an unoccupied space within 120 feet of him. Alternatively, he can choose a space within range that is occupied by a Large or smaller creature or object. If it's a creature that is willing, they both teleport, swapping places. If it's a creature that is unwilling, it must succeed on a DC 24 Constitution saving throw, or be teleported in the same way. An object automatically fails the saving throw.

Telekinesis. Abraxas targets a creature or an object that he can see within 120 feet of him, wheighing up to 1000 pounds. If the target is a creature, it must succeed on a DC 26 Strength saving throw or be restrained in Abraxas’s telekinetic grip until the start of his next turn, or until Abraxas is incapacitated. At the end of Abraxas’s turn it takes 27 (5d10) force damage, and he can move it up to 60 feet in any direction, but not beyond 120 feet of himself.

If the target is an object, which isn't being worn or carried, it is moved up to 60 feet in any direction, but not beyond 120 feet of himself. Abraxas can also exert fine control on objects with his telekinesis, such as manipulating a simple tool or opening a door or a container. 

Aspect of Abraxas 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. Aspect of Abraxas regains spent legendary actions at the start of its turn.

Galactic Longsword. Abraxas makes one Galactic Longsword attack.

Teleport (Costs 2 Actions). Abraxas uses his Teleport action, or he forces a creature that he can see within 90 feet of him to make a DC 24 Constitution saving throw. On a failed save they are teleported in the same manner to an unoccupied space he can see.

Sweeping Edge (Costs 2 Actions). Abraxas extends his blade's length further and sweeps it in a 20-foot cone. All creatures in the area must make a DC 25 Dexterity saving throw, taking 60 (9d10 + 11) force damage and be knocked prone on a failed save, or half as much damage on a successful one and they aren't knocked prone.
