Improved Breath Weapon

One's draconic heritage can manifest itself in different ways. For some, they might develop tougher scales to defend against oncoming attacks while others might grow wings to fly at incredible speeds. For you, the strength of your breath weapon has increased to become more versatile and damaging. Your breath weapon attack now does 5d6 damage of your chosen lineage and scales up whenever you reach certain levels. The damage will increase to 6d6 at level 6, 7d6 at level 11, and 8d6 at level 16.

Second, when you use an action to attack with the breath weapon, you can choose to use half or a third of your damage dice to make an attack and gain another use of your breath weapon(ex. If your level 6, you can choose to use 3d6 of your breath weapon's damage instead of the full amount giving two uses of the attack or you can split it further and use 2d6 of the full damage gaining three uses).

Although, since your breath weapon has become powerful, it now requires an extra amount of time to come back. If the full amount of damage is used, your breath weapon will come back on a long rest while other expended uses will return on a short rest.
