Primal Dragon

You prefer your meat fresh and your combat personal.  You gain a bite attack that deals 1d4+strength piercing damage.  When you take the attack action, you may use a bonus action to make an attack with your bite.  At fifth level, you may charge your bite with the same element as your breath weapon.  When you do, you deal a bonus 1d6 damage of that element and the bite damage is considered magical.  Using your breath weapon removes the bonus elemental damage until you take a short or long rest.
