Crakula

Keen Sight and Smell. Crakula has advantage on Wisdom (Perception) checks that rely on sight or smell.

Unusual Nature. Crakula doesn’t require air.

Vampire Weaknesses. Crakula has the following flaws:

Enraged by Celestial. If it hears words of Celestial spoken, Crakula must try to attack the source of those spoken words on its next turn. If these words come from multiple sources and from opposite directions, the vampire is restrained. Otherwise, it moves to attack what it perceives to be the closest source.

Repulsed by Perfume. Crakula has disadvantage on melee attack rolls made against any creature wearing perfume or carrying an open container of it.

Stake to the Heart. If a piercing weapon made of wood is driven into the Crakula's heart while Crakula is incapacitated in its resting place, the vampire is paralyzed until the stake is removed.

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

Blood Hunger. Crakula thirst for blood instead and if Crakula does not feed on one litre of blood every 48 hours, Crakula will lose control and attack the nearest source of Blood

Multiattack. Crakula makes two attacks: one with its beak and one with its claws.

Beak. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 10 (1d10 + 5) piercing damage.

Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) slashing damage.

Vampiric Bite.  Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit: 12 (2d6 + 5) piercing damage plus 9 (2d8) necrotic damage. The target’s hit point maximum is reduced by an amount equal to the necrotic damage taken, and Crakula 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.
