Anastrasya von Zarovich

Bride of Strahd. While Strahd can take Lair Actions, Anastrasya can benefit from them. If Strahd chooses his first Lair Action, Anastrasya can pass through the solid walls, floors, ceilings and doors of Castle Ravenloft as if they weren't there. Anastrasya only has this ability as long as Strahd allows it.

Regeneration. Anastrasya regains 15 hit points at the start of its turn if she has at least 1 hit point and isn't in sunlight or running water. If Anastrasya takes Radiant damage or damage from holy water, this trait doesn't function at the start of Anastrasya's next turn.

Guarded Mind. Anastrasya's mind and emotions cannot be read.

Spider Climb. Anastrasya can climb difficult surfaces, including along ceilings, without needing to make an ability check.

Vampire Weakness. Anastrasya has these weaknesses:

Forbiddance. Anastrasya can’t enter a residence without an invitation from an occupant.
Running Water. Anastrasya takes 20 Acid damage if it ends its turn in running water.
Stake to the Heart. Anastrasya is destroyed if a weapon that deals Piercing damage is driven into Anastrasya’s heart while Anastrasya has the Incapacitated condition.
Sunlight. Anastrasya takes 20 Radiant damage if she starts her turn in sunlight. While in sunlight, she has Disadvantage on attack rolls and ability checks.

Multiattack. Anastrasya makes two Claw attacks and uses Bite.

Claw. Melee Attack Roll: +6, reach 5 ft. Hit: 8 (2d4 + 3) Slashing damage. If the target is a Medium or smaller creature, it has the Grappled condition (escape DC 13) from one of two claws.

Bite. Constitution Saving Throw: DC 14, one creature within 5 feet that is willing or that has the Grappled, Incapacitated, or Restrained condition. Failure: 6 (1d6 + 3) Piercing damage plus 7 (2d6) Necrotic damage. The target’s Hit Point maximum decreases by an amount equal to the Necrotic damage taken, and Anastrasya regains Hit Points equal to that amount.

Charm. Anastrasya targets one humanoid she can see within 30 feet of her. If the target can see Anastrasya, the target must succeed on a DC 16 Wisdom saving throw against this magic or be charmed. The charmed target regards Anastrasya as a trusted friend to be heeded and protected. The target isn't under Anastrasya's control, but it takes Anastrasya's requests and actions in the most favorable way and lets Anastrasya bite it. Each time Anastrasya or her companions do anything harmful to the target, it can repeat the saving throw, ending the effect on itself on a success. Otherwise, the effect lasts for 1 hour or until Anastrasya is destroyed, is on a different plane of existence than the target, or takes a bonus action to end the effect.

Children of the Night (1/day). Anastrasya magically calls 1d4 swarms of bats or rats, provided that the sun isn't up. The called creatures arrive in 1d4 rounds, acting as allies of Anastrasya and obeying her spoken commands. The beasts remain for 1 hour, until Anastrasya dies, or until she dismisses them as a bonus action.

Deathless Agility. Anastrasya takes the Dash or Disengage action.

Misty Step (Recharge 5-6). As a bonus action, Anastrasya disappears in shadowy mist and teleports up to 30 feet to an unoccupied space she can see.
