Soul Leech. The undead raven drains the life force of a living creature it is perched upon. The target must succeed on a DC 12 Constitution saving throw or take 7 (2d6) necrotic damage and the raven gains temporary hit points equal to the damage dealt. On a successful saving throw, the target takes half damage, and the raven doesn't gain any temporary hit points.

Evasion: If the undead raven is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

Deathly Peck: Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage.

Screech: The undead raven emits a piercing screech. Each creature within 30 feet of the raven must make a DC 12 Wisdom saving throw or be frightened until the end of their next turn. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
