Regeneration. Virelda regains 10 hit points at the start of her turn if she has at least 1 hit point and isn't in sunlight or running water.

Sorcerous Blood (Necrotic Affinity). When Virelda casts a spell that deals necrotic damage, she can reroll any 1 on the damage dice, but must use the new result.

Legendary Resistance (3/Day, or 4/Day in Lair). If the vampire fails a saving throw, it can choose to succeed instead.

Shadow Drift (Recharge 5–6). As an action, Virelda becomes partially insubstantial for 1 minute or until she ends it as a bonus action.

While insubstantial: She can move through other creatures' spaces as if they were difficult terrain. She doesn’t provoke opportunity attacks and has resistance to all damage. She cannot use physical attacks but can cast spells and maintain concentration. Her movement becomes silent and leaves behind wisps of shadow. If she ends her turn inside a creature's space, she is shunted to the nearest unoccupied space and takes 1d10 force damage.

"You try to strike me, but I’m already gone."

Vampire Weakness. The vampire has these weaknesses:

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

Sanguine Drain. Constitution Saving Throw: DC 18, one creature the vampire can see within 30 feet that isn’t a Construct or an Undead. Failure: 14 (4d6) Necrotic damage. The target’s Hit Point maximum decreases by an amount equal to the damage taken, and the vampire regains Hit Points equal to that amount.

Command Thrall (recharge 5-6). Virelda speaks a single resonant word of domination that vibrates through the puppet’s nerves.

Prerequisite: Virelda must have line of sight to a creature currently being puppeted by the Crawling Claw of Nocturne.

Prerequisite: The Crawling Claw must be in play, if the Crawling Claw is destroyed  Virelda loses access to Command Thrall.

Choose one creature puppeted by the Crawling Claw within 60 feet. That creature immediately uses its reaction (or best available movement/action if no reaction remains) to perform one of the following:

• Move up to its speed in a direction Virelda chooses (without provoking opportunity attacks).

• Make one weapon attack against a creature of Virelda’s choice.

• Cast a cantrip it knows at a target Virelda chooses (if the thrall is a spellcaster).

• Drop held items or pick up a visible object.

• Grapple a target within reach.

• Take no action but obey a stated command on their next turn.

If Virelda is below 50% HP: Command Thrall recharges on a 3–6 instead of 4–6.

The thrall does not get a saving throw — the Claw overrides its nervous system completely during this command.

If the thrall is a PC:
They are still aware of their actions happening but cannot control their body. Their vision dims around the edges as if seen through a tunnel of violet light.

Legendary Action Uses: 2 (3 in Lair): Immediately after another creature’s turn, the vampire can expend a use to take one of the following actions. The vampire regains all expended uses at the start of each of its turns.

Beguile: The vampire casts Command, requiring no spell components and using Charisma as the spellcasting ability (spell save DC 18). The vampire can’t take this action again until the start of its next turn.

Umbral Strike: The vampire moves up to half its Speed, and it makes one Necrotic Lash or Sickening Ray attack.

Dark Whispers: Cast Chill Touch or Message.

Haunting Glare: One creature within 30 ft. must succeed on a DC 13 Wisdom save or be frightened until end of its next turn.

Blood Echo (Costs 2): Reuse any 1st-level spell she cast this turn without expending a slot.

Summon the Withered Dolls (Costs 2 Actions): Virelda whispers a forgotten rhyme, and from the shadows or crumpled cloaks of the fallen, small, faceless dolls stitch themselves together with thread made of shadow and sorrow. Effect: Virelda summons 1d4 + 2 Withered Dolls in unoccupied spaces within 30 feet of her. They immediately act after her initiative and follow her mental commands.

Veil of Echoes (Costs 2 Actions): Virelda summons two illusory duplicates of herself within 10 feet. These duplicates appear identical and mimic her movements eerily.

Swap Step (Bonus Action): On her turn, Virelda may swap places with one of the duplicates. This teleportation does not provoke opportunity attacks.

Echoed Presence: While duplicates are active, her voice issues from all three forms simultaneously, creating a haunting, disorienting effect. She may cast any spell from her own location or from the position of a duplicate (range measured from that location).

Phantom Defenses: Each duplicate shares Virelda’s AC and saving throws. A duplicate is destroyed if it takes any damage.

Shatter the Illusion: A creature that successfully damages a duplicate knows which is the real Virelda until the start of her next turn.

Only two duplicates may exist at a time. They vanish if Virelda is incapacitated or dismisses them as a bonus action.
