Dragon Mantle

As an action you summon ghostly dragon limbs over your body. Depending upon the construct, your attacks will cause one of the following effects.

Claws. When you make a melee attack, you do an additional 2d6 magical slashing damage.

Tail. You can as a bonus action make a sweeping spell attack on up to 3 creatures you can see within 10 feet of you for 1d8 magical bludgeoning damage to each creature.

Wings. Using an action, each creature within 15 feet must succeed on a Dexterity saving throw against your spell save DC or take 1d10 bludgeoning damage. A successful save takes only half damage.

At Higher Levels. 
When you cast this spell using a spell slot of 3rd level or higher, the damage die increases by 1 for every two slot levels above 2nd. At 5th level each option gains an additional effect. Claws add your spell modifier. Tail knocks creatures one size larger than you prone. Wings give you a fly speed of 15 feet and you don't take attacks of opportunity until the start of your next turn.
