Draconic Savagery

When you make an attack on your turn or use your action to use your breath weapon, you can use your bonus action to make an attack with your jaws.  On a hit, it deals an additional 1d4 damage of the damage type you choose for your Draconic Ancestry.  This additional damage increases to 2d4 at level 6, 3d4 at level 11, and 4d4 at level 16.  Once you make this attack, you can't do so again until you finish a short or long rest.
