Shapechanger. Dracula can use his action to polymorph into a Tiny bat, a Medium wolf, or a Medium vampiric mist, or back into his true form.

While in bat or wolf form, Dracula can’t speak. In bat form, his walking speed is 5 feet, and he has a flying speed of 30 feet. In wolf form, his walking speed is 40 feet. His statistics, other than his size and speed, are unchanged. Anything he is wearing transforms with him, but nothing he is carrying does. He reverts to his true form if he dies.

Legendary Resistance (3/Day). If Dracula fails a saving throw, he can choose to succeed instead.

Misty Escape. When Dracula drops to 0 hit points outside his coffin, he transforms into a cloud of mist (as in the Shapechanger trait) instead of falling unconscious. 

While he has 0 hit points in mist form, he can’t revert to his vampire form, and he must reach his coffin within 2 hours or be destroyed. Once in his coffin, he reverts to his vampire form. He is then paralyzed until he regains at least 1 hit point. After 1 hour in his coffin with 0 hit points, he regains 1 hit point.

Regeneration. Dracula regains 20 hit points at the start of his turn if he has at least 1 hit point. If he takes radiant damage or damage from holy water, this trait doesn’t function at the start of his next turn.

Spellcasting. Dracula is a 20th-level spellcaster. His spellcasting ability is Intelligence (spell save DC 18, +10 to hit with spell attacks). He has the following wizard spells prepared:

Cantrips (at will): mage hand, prestidigitation, ray of frost, eldritch blast, 

1st level (4 slots):comprehend languages, fog cloud, sleep, shield

2nd level (3 slots): detect thoughts, gust of wind, mirror image, alter self

3rd level (3 slots): animate dead, fireball, nondetection

4th level (3 slots): blight, greater invisibility, polymorph

6th level (2 slots): create undead, mage hand, true seeing, disintegrate

7th level (2 slots): finger of death, teleport, simulacrum, plane shift

8th level (1 slot): mind blank, control weather

9th level (1 slot): imprisonment, true polymorph

Spider Climb. Dracula can climb difficult surfaces, including upside down on ceilings, without having to make an ability check.

Vampire Weaknesses. Dracula has the following flaws:

Forbiddance. He can’t enter a residence without an invitation from one of the occupants.

Stake to the Heart. If a piercing weapon made of wood is driven into his heart while he is incapacitated in his coffin, he is paralyzed until the stake is removed.

Multiattack (Vampire Form Only). Dracula makes three attacks, only one of which can be a bite attack.

Unarmed Strike (Vampire or Wolf Form Only). Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 8) slashing damage plus 14 (5d8) necrotic damage. If the target is a creature, Dracula can grapple it (escape DC 18) instead of dealing the slashing damage.

Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one willing creature, or a creature that is grappled by Dracula, incapacitated, or restrained. Hit: 7 (1d6 + 4) piercing damage plus 10 (3d6) necrotic damage. The target’s hit point maximum is reduced by an amount equal to the necrotic damage taken, and Dracula regains hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if its hit point maximum is reduced to 0. A humanoid slain in this way and then buried in the ground rises the following night as a vampire spawn under Dracula's control.

Charm. Dracula targets one humanoid he can see within 30 feet of him. If the target can see Dracula , the target must succeed on a DC 17 Wisdom saving throw against this magic or be charmed. The charmed target regards Dracula as a trusted friend to be heeded and protected. The target isn’t under Dracula's control, but it takes Dracula's requests and actions in the most favorable way and lets Dracula bite it.

Each time Dracula or his 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 24 hours or until Dracula 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). Dracula magically calls 2d4 swarms of bats or swarms of rats, provided that the sun isn’t up. While outdoors, Dracula can call 3d6 wolves instead. The called creatures arrive in 1d4 rounds, acting as allies of Dracula and obeying his spoken commands. The beasts remain for 1 hour, until Dracula dies, or until he dismisses them as a bonus action.

Dracula can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Dracula regains spent legendary actions at the start of his turn.

Move. Dracula moves up to his speed without provoking opportunity attacks.

Unarmed Strike. Dracula makes one unarmed strike.

Bite (Costs 2 Actions). Dracula makes one bite attack.
