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

While in bat form, Beundock can’t speak, his walking speed is 5 feet, and it has a flying speed of 30 feet. Its statistics, other than its size and speed, are unchanged. Anything it is wearing transforms with it, but nothing it is carrying does. It reverts to its true form if it dies.

While in mist form, Beundock 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 it can’t pass through water. he has advantage on Strength, Dexterity, and Constitution saving throws, and is immune to all nonmagical damage, except the damage it takes from sunlight.

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

Misty Escape. WhenBeundock drops to 0 hit points outside its resting place,Beundock transforms into a cloud of mist (as in the Shapechanger trait) instead of falling unconscious, provided that he isn’t in sunlight or running water. If he can’t transform, he is destroyed.

Regeneration. Beundock regains 20 hit points at the start of his turn if it has at least 1 hit point and isn’t in sunlight or running water. If Beundock takes radiant damage or damage from holy water, this trait doesn’t function at the start of the vampire’s next turn.

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

Vampire Weaknesses. Beundock has the following flaws:

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

Harmed by Running Water. Beundock takes 20 acid damage if it ends its turn in running water.

Stake to the Heart. If a piercing weapon made of wood is driven into Beundocks heart while he is incapacitated in its resting place, Beundock is paralyzed until the stake is removed.

Sunlight Hypersensitivity. Beundock takes 20 radiant damage when he starts his turn in sunlight. While in sunlight, it has disadvantage on attack rolls and ability checks.

Multiattack.

Beundock makes two melee attacks with his Claws of Dissonance, or he makes one melee attack and uses a Bardic Action or casts a spell as an action and a Cantrip as a bonus action.

Claws of Dissonance
+8 to hit, reach 5 ft., one target
Hit: 13 (2d8 + 4) slashing damage + 4 (1d8) psychic damage.

Charm. Beundock targets one humanoid it can see within 30 feet of it. If the target can see Beundock , the target must succeed on a DC 16 Wisdom saving throw against this magic or be charmed by Beundock . The charmed target regards Beundock  as a trusted friend to be heeded and protected. Although the target isn’t under Beundock's  control, it takes Beundock's  requests or actions in the most favorable way it can, and it is a willing target for Beundock to drain of blood.

Each time Beundock or Beundock ’s 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 Beundock  is destroyed, is on a different plane of existence than the target, or takes a bonus action to end the effect.

Beundock 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. Beundock regains spent legendary actions at the start of its turn.

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

Claws of Dissonance. Beundock makes one unarmed strike.

Cast Spell (3 legendary actions). Beundock can cast any spell of level 5 or
