Adamantine Wings (EFA - A)

You feel an instant of searing pain as you sprout a pair of gleaming wings made of overlapping feathers of dark, dull metal.

The wings grant you a fly speed of 60 feet. If you are not flying, as an action you can make 2 attacks, 1 with each wing. You are proficient with your wings. Each wing deals 2d6 slashing damage. The wings are considered both magical and adamantine for the purposes of overcoming damage reduction. In addition, as an action, you can choose to launch the wings' feathers as a 60-foot cone of razor-sharp blades. Each creature within the cone must make a Dexterity saving throw. A creature takes 10d6 slashing damage on a failed save, and half as much damage on a successful one. After you use this attack, the spell ends.
