Void Disciple

A focused strike that momentarily unravels a creature's form. When you hit with a weapon attack, you can expend 1 Void Point to deal an extra 1d8 necrotic damage. At 5th level, this extra damage increases to 2d8; at 11th level to 3d8; at 17th level to 4d8. If the target is concentrating, it must succeed on a Constitution save (DC = 8 + your proficiency + your Wisdom modifier) or lose concentration.

You reach into the between and bind a creature to a point. As a bonus action, expend 1 Void Point to make a ranged spell-like touch (30 feet). On a hit the target must succeed on a Strength saving throw or be restrained until the end of your next turn. A large or larger creature has advantage on the save.

You step into the Between and reappear a short distance away. As a bonus action, spend 1 Void Point to teleport up to 30 feet to an unoccupied space you can see. You can move through spaces as narrow as 1 inch wide while making this teleportation, but you must appear in a space large enough for you.

As an action you make a melee spell attack. On a hit the target takes 2d6 necrotic damage and is afflicted by Entropy: the target's next attack roll or saving throw within 1 minute has disadvantage unless it succeeds on a Constitution saving throw. At 5th level damage increases to 3d6, at 11th to 4d6, at 17th to 5d6.

You carve a corridor of nothingness in a straight line up to 30 feet long and 10 feet wide. As an action, spend 2 Void Points to create the corridor (concentration, up to 1 minute). Creatures inside the corridor cannot cast spells with vocal components and any creature concentrating that enters the corridor must make a Constitution save or lose concentration.

As an action, expend 1 Void Point to choose a creature within 30 feet. The target must succeed on a Strength saving throw or be pulled up to 20 feet straight toward you and knocked prone if it ends its movement adjacent to you. If the save succeeds the target isn't pulled.

You extend the range of your weapon with the Between. As a bonus action, spend 1 Void Point to increase the reach of your melee attacks by 10 feet for 1 minute. While active your melee attacks deal an extra 1d6 necrotic damage (scales to 2d6 at 11th level).

You can force a region of space to crumple. As an action, expend 3 Void Points to create a 15-foot-radius area centered on a point within 60 feet that pulls creatures toward the center. Each creature in the area must make a Strength save; on a failure it is pulled 10 feet toward the center and takes 3d8 force damage (half on success and not pulled). At 11th level damage increases to 4d8, at 17th to 6d8.

You cause a target to forget its most recent action. As an action, spend 2 Void Points and target one creature you can see within 30 feet. The target must succeed on an Intelligence saving throw or have its last turn's grant erased: it suffers disadvantage on attack rolls and ability checks until the end of its next turn and cannot benefit from features that triggered on its last turn (such as extra attacks that depended on prior conditions).

When you are targeted by a spell or special effect that deals damage or imposes a condition, you can spend 2 Void Points to impose disadvantage on the attack or to force the caster to reroll the save DC against you (you choose which) — if the reroll fails, the effect is negated for you. Usable as a reaction.

You step almost entirely into the Between for a brief period. As an action you can spend 3 Void Points to become ethereal-like for one round: you can move through creatures and objects as though difficult terrain (but cannot end your turn inside objects), and you gain advantage on Dexterity saving throws. Attacking or casting a spell ends the effect.

You condense a persistent well of nothing. As an action (4 Void Points) create a 10-foot-radius sphere of roiling nothing at a point within 60 feet. Creatures that start their turn there take 6d8 necrotic damage (Dex save halves) and have their healing suppressed for 1 minute. The area lasts for concentration, up to 1 minute. You can maintain only one Singularity at a time.

Desperate usage of the Between. As an action you may sacrifice hit points up to half your current hit point maximum to gain 1 Void Point per 5 HP spent (minimum 5 HP spent). This does not heal you and cannot raise you above your hit point maximum.

When you use Collapse while wielding a melee weapon, expend an additional Void Point to cause edges of the collapsed space to tear at flesh: each creature pulled that fails its save takes an extra 2d8 necrotic damage.
