Your Bronze Dragon heritage empowers your arcane abilities and natural talents. 

Ability Score Increase- Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.

Anima Infusion- If you cast a spell that deals lightning damage on your turn, you may use a free action to spend a sorcery point. When you do, add your proficiency bonus to your AC until the start of your next turn. 

Lightning Droméas- Rather than using an action to Dash, you may instead use a bonus action. You may Dash this way a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a long rest. 

Draconis Mentis- Whenever you take damage while concentrating on a spell, you may use your reaction to gain advantage on Constitution saving throws that you make to maintain your concentration until your next turn.
