Claws of the Dragon

Using your sorcerous bloodline, you can grow a set of menacing claws with which to damage your foes. For the duration, your unarmed strikes deal 1d4 slashing damage. Your claws are considered to be light for the purpose of two-weapon fighting and you use your spellcasting modifier for attack and damage rolls.

At Higher Levels. The spell’s damage increases by one die when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
