You can tap into your Dragon heritage and can manipulate your Breath Weapon it in new ways.

+1 to Charisma or Strength or Constitution

Gives Draconic Bloodline Sorcerer a breath weapon. When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of magical energy. Each creature in that area must make a Dexterity saving throw (DC = 8 + your Constitution modifier or Charisma + your proficiency bonus). On a failed save, the creature takes 1d10 damage of the type associated with your Metallic Ancestry. On a successful save, it takes half as much damage. This damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10). You can use your Breath Weapon a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

If you are a Dragonborn and a Draconic Bloodline Sorcerer you only have one breath weapon but you can pick Constitution or Charisma for your save DC (DC = 8 + your Constitution modifier or Charisma + your proficiency bonus).

You can now switch our Breath Weapon to 3 different range types:

• 15feet cone
• 30 feet line
• 10 feet radius around the character

In addition if you are a Dragonborn and a Draconic Bloodline Sorcerer you can pick one additional breath weapon damage type.
