Vorvolaka

Any hostile creature that starts its turn within 20 feet of the vorvolaka must succeed on a DC 18 Wisdom saving throw or have Frightened condition until the start of the creature's next turn. If a creature's saving throw is successful, they're immune to the vorvolaka's Fear Aura for the next 24 hours. This ability does not function if the vorvolaka is Unconscious.

The vorvolaka has advantage on saving throws against spells and other magical effects.

The vorvolaka regains 15 hit points at the start of its turn if it has at least 1 hit point. If the vorvolaka takes Radiant damage, this trait doesn't function at the start of the vorvolaka's next turn.

The vorvolaka makes two Talon attacks. It can replace one of the attacks with Rend Armor (if available).

Melee Weapon Attack +9 to hit, reach 5 ft., one target. 22 (4d8 + 4) Piercing damage plus 14 (4d6) Necrotic damage.

The vorvolaka makes a Talon attack against a creature. On a hit, the creature's AC is reduced by 2 for 1 minute. Creatures not wearing armor are immune to this effect, and the total reduction can't bring a creature below an AC of 10.
