The Black Oath

You speak the forgotten oaths of a buried tyrant, binding a creature’s soul in iron and grief. Choose a creature within range. That target must succeed on a Charisma saving throw or become cursed, shackled to your will.

While cursed:

• The target’s speed is halved.

• It cannot regain hit points.

• It suffers psychic damage equal to half the damage it deals.

• If it dies under the curse, it rises 1 minute later as a wraith under your control (per Create Undead), even if normally immune to necromancy.

This spell can only affect one creature at a time. Ending concentration ends the curse, but not any undead it creates.
