You have to pick a dragon type you are related to that determines the shape and type of damage of your breath weapon and they type of resistance you have.
Dragon Breath : 2d6 that scales up to 5d6 at 16th level, DC is 8+con mod+prof bonus, save for half damage, recharges with a short rest, it is an action to use it.
Resistance to the type of energy you breath.
