This spell causes you to sprout forth a pair of skeletal wings from your back for the duration of the spell. You gain a flying speed equal to your walking speed.   If you cast this spell while wearing armor, the spell automatically fails unless the armor is made to accommodate the wings, and clothing not made to accommodate your wings might be destroyed when you cast this spell.   Additionally, as an action, you can cause your skeletal wings to unleash a shower of sharp bone shards upon your foes. Each creature in a 30-foot cone must make a Dexterity saving throw, taking 5d6 piercing damage on a failed save, or half as much damage on a successful one.   When you use this action, you lose your flying speed until the start of your next turn as the skeletal wings reform. If you’re in the air when you use this action or when the spell ends, you fall if nothing else is holding you aloft.
