Traits

Magic Resistance. The hazvongel has advantage on saving throws against spells and other magical effects.

Actions

Multiattack. The hazvongel makes three Talon attacks.

Talon. Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit:18 (3d8 + 5) piercing damage.

Blood Barrage (Recharge 5–6). The hazvongel launches a spray of blood in a 90-foot cone. Each creature in that area must make a DC 18 Dexterity saving throw, taking 27 (6d8) necrotic damage on a failed save or half as much damage on a successful one.

Lore

They make excellent scouts and are capable aerial attackers, but their attention span is frustratingly wanting.
