Multiattack (Vampire Form Only)
Unarmed Strike (Vampire or Wolf Form Only). Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage plus 14 (4d6) necrotic damage. If the target is a creature, Strahd 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 Strahd, incapacitated, or restrained. Hit: 7 (1d6 + 4) piercing damage plus 10 (3d6) necrotic damage.
Charm. Strahd targets one humanoid he can see within 30 feet of him. If the target can see Strahd, the target must succeed on a DC 17 Wisdom saving throw against this magic or be charmed.
Children of the Night (1/Day). Strahd magically calls 2d4 swarms of bats or swarms of rats, provided that the sun isn’t up. While outdoors, Strahd can call 3d6 wolves instead.

Shapechanger. If Strahd isn’t in running water or sunlight, he can use his action to polymorph into a Tiny bat, a Medium wolf, or a Medium cloud of mist, or back into his true form. While in bat or wolf form, Strahd 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.

While in mist form, Strahd can’t take any actions, speak, or manipulate objects. He is weightless, has a flying speed of 20 feet, can hover, and can enter a hostile creature’s space and stop there. In addition, if air can pass through a space, the mist can do so without squeezing, and he can’t pass through water. He has advantage on Strength, Dexterity, and Constitution saving throws, and he is immune to all nonmagical damage, except the damage he takes from sunlight.

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

Misty Escape. When Strahd drops to 0 hit points outside his coffin, he transforms into a cloud of mist (as in the Shapechanger trait) instead of falling unconscious, provided that he isn’t in running water or sunlight. If he can’t transform, he is destroyed.
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. Strahd regains 20 hit points at the start of his turn if he has at least 1 hit point and isn’t in running water or sunlight. If he takes radiant damage or damage from holy water, this trait doesn’t function at the start of his next turn.

Strahd 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. Strahd regains spent legendary actions at the start of his turn.

Move: Strahd moves up to his speed without provoking opportunity attacks.
Unarmed Strike: Strahd makes one unarmed strike.
Bite (Costs 2 Actions): Strahd makes one bite attack.
