Bruxa

Shapechanger. The bruxa can use its action to polymorph into a human form, or back into its true vampiric form.

Legendary Resistance (3/Day). If the bruxa fails a saving throw, it can choose to succeed instead.

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

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

Multiattack. (Vampire Form Only). The bruxa makes two attacks, only one of which can be a bite attack.

Claws (Vampire Form Only). Melee Weapon Attack: +9 to hit, reach 5 ft., one creature. Hit: 17 (3d8 + 4) slashing damage. Instead of dealing damage, the bruxa can grapple the target (escape DC 18).

Bite. (Vampire Form Only). Melee Weapon Attack: +9 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the vampire, 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 the vampire regains hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.

Piercing Scream.  As an action the bruxa can let off a piercing scream, range 15ft cone, any creature caught in the scream must make a Strength saving throw (DC 16). On a failure the creature is sent flying back 15ft and falls prone. On a success the creature keeps its footing and is unaffected.

The vampire 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. The vampire regains spent legendary actions at the start of its turn.

Move. The vampire moves up to its speed without provoking opportunity attacks.

Invisibility. The bruxa can use its action to cast greater invisibility. If the bruxa unwillingy loses concentration on the spell it can not recast the spell for one turn.
