Traits

Sigil of Fracture (Recharge 5–6).
As a bonus action, the Voidmancer can place a spatial rupture sigil at a point within 60 ft. The sigil pulses with invisible energy. When any creature enters or starts its turn within 10 ft. of it, they must make a DC 15 Constitution save or take 9 (2d8) force damage and have their speed halved until the end of their next turn. The sigil lasts for 1 minute or until dispelled.

Void-Threaded Mind.
The Voidmancer has advantage on saving throws against illusion, psychic damage, and effects that would read or alter its thoughts (such as Detect Thoughts or Suggestion).

Planar Synthesis.
While within a demiplane or non-material realm (like Barovia), the Voidmancer’s spells ignore resistance to force, psychic, or necrotic damage.

Actions

Void Lash (Cantrip).
Melee Spell Attack: +7 to hit, reach 10 ft., one creature.
Hit: 13 (3d6 + 3) force damage. If the target is Large or smaller, it must succeed on a DC 15 Strength save or be pulled 10 feet toward the Voidmancer.
