Traits

Blood Witch Dance. The witch can use a bonus action to control the movement of one creature cursed by its hex spell that it can see within 30 feet of it. The creature must succeed on a DC 15 Charisma saving throw or use its reaction to move up to 30 feet in a direction of the witch's choice.

Devil's Sight. Magical darkness doesn't impede the witch's darkvision.

Spellcasting

Innate Spellcasting. The witch's innate spellcasting ability is Charisma (spell save DC 15, +7 to hit with spell attacks). The witch can innately cast the following spells, requiring no material components:

At will: alter self, detect magic, eldritch blast (at 11th level), false life, levitate (self only), mage armor (self only)

1/day each: circle of death, enthrall, suggestion

3/day each: hellish rebuke, hex, scorching ray (at 3rd level)

Actions

Shortsword. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit:6 (1d6 + 3) piercing damage.

Lore

Blood witches imagine themselves to be the intermediaries between Rakdos and his cult-the pinnacle of his priesthood, his trusted advisors, and the messengers who communicate his will to the scattered troupes and ringmasters. The Cult of Rakdos recognizes no authority but Rakdos, and the demon lord requires no advisors. Nonetheless, the blood witches are smart, charismatic, and powerful, so their voices do carry some weight.
