Become Nightwing

This spell imbues you with wings of shadow. For the duration of the spell, you gain a flying speed of 60 feet and a new attack action: Nightwing Breath.
Nightwing Breath (Recharge 4–6): You exhale shadow-substance in a 30-foot cone. Each creature in the area takes 5d6 necrotic damage, or half the damage with a successful Dexterity saving throw.
