Spell Resistance. Void has resistance to damage dealt by spells.

Causal Awareness. Creatures attempting to attack Void do so with disadvantage, and Void has advantage on saving throws. If the creature would have advantage when attacking void, then the advantage cancels out the disadvantage and the creature attacks as normal.

Eldritch Mind. Void automatically succeeds on Intelligence checks and saving throws.

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

Mind Probe. Void targets a creature within 300 feet. Void does not need to be able to see the creature, he only needs to know a creature is there, such as described by the detect thoughts spell. That creature must make a DC 22 Intelligence save; on a failure, Void understands their personality traits, ideals, bonds, and flaws. Additionally, Void can read their surface thoughts for one day.

Invocation of Doom. Void chooses up to one hundred creatures within 600 feet of himself; they must succeed on a DC 25 Constitution save or become marked by the Mark of Sacrifice. A creatures' very soul is affected by the Mark, and it cannot be removed by any means. While marked, creatures suffer from the following effects: 

• All Undead, Fiends, and Aberrations are aware of the marked creatures' location while it is within 120 feet of them. These creatures are drawn to the Mark, and seek to destroy the Marked person. 
• Lose 5 HP per turn when within 50 feet of a creature of one of the above types. This effect can only take the creature down to a minimum of 50 HP, once the creature is at 50 HP or less; they stop taking damage until they regain more HP.
• Take an additional 10 damage if hit by a member of the God Hand.
• The God Hand are aware of your location, no matter what.

Invoke Despair. Void telepathically projects images of the horrors of existence onto the mind of a creature within 120 feet of himself. That creature must make a DC 22 Wisdom saving throw; on a failure, they fall prone and become stunned. They may make this save at the end of each of their turns. On a success, that creature is immune to this ability for 24 hours.

Claw. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 18 (4d6 + 4) slashing damage, plus 18 (4d8) necrotic damage.

Counterspell. Void can see the flow of causality, and negate spells with ease.

Spatial Manipulation. Void can defend himself by bending space. When Void is hit by an attack but before damage is rolled, he can use his reaction to choose new targets for the attack. The attack is treated as though it originated from his space. The creature that made the attack must then roll to hit against the new target. Ranged attacks are made with disadvantage. 

Void can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creatures turn. Void regains spent legendary actions at the start of his turn.

Spatial Distortion (Costs 1 Action). Each creature within 300 feet of Void must make a DC 22 Dexterity saving throw. On a failure, Void teleports them to an unoccupied space within a 300 foot radius of himself.

Teleport (Costs 1 Action). Void uses his teleport action.

Claw (Costs 1 Action). Void makes a Claw attack.
