Increase your Stength score by 2 and your Charisma score by 1

You can manifest the power of your draconic ancestor. Choose a damage type from fire, cold, acid, poison and lightning. You are resistant to that type of damage and you can deal an extra 1d4 (1d6 lvl 5, 1d8 lvl 10) of that type of damage each turn to a creature you hit.

Once per short or long rest, as an action, you can roar and manifest ethereal dragon wings, gaining flying speed equal to your walking speed, which last for minutes equal to your proficiency bonus. The roar frightens any hostile creatures which are within 60 ft. of you and can hear you (DC 8 + PB + your Charisma score Wisdom save to avoid this effect). If your wings disappear while you are in the air, you fall to the ground.

You know how to speak, read and write Draconic and Common.
