Primal Savagery

Your teeth or fingernails lengthen and sharpen. You choose which. Make a melee spell attack against one creature within 5 feet of you. On a hit, the target takes 1d10 piercing or slashing damage (your choice). After you make the attack, your teeth or fingernails return to normal.

The spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
