Draconic Morphosis

You may have had a lot of contact with dragons or perhaps even have draconic ancestry yourself. Either way, you have learned to use magic to temporarily morph parts of yourself to mimic a dragon. Your fingernails grow into sharp, stout draconic claws, and your breath becomes that of your draconic affiliation, ready to deliver a savage attack. Make a melee spell attack against one creature within 5 feet of you. On a hit, the target takes 2d4 slashing damage and 1d4 elemental damage based on the type of dragon you are affiliated with. After you make the attack, the claws revert back into your fingernails.

The spell’s damage increases by 2d4 when you reach 5th level (4d4), 11th level (6d4), and 17th level (8d4).
