Blood Burst

You can cause a burst of blood to erupt from a creature that you can see within 30 feet of you. The creature must make a Constitution saving throw. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus. On a failed save, the creature takes 2d6 necrotic damage and is blinded until the end of your next turn. On a successful save, the creature takes half as much damage and isn’t blinded.
