race features:
Breath Weapon. When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of magical energy in a 30-foot line that is 5 feet wide. Each creature in that area must make a Dexterity saving throw (DC = 8 + your Constitution modifier + your proficiency bonus). On a failed save, the creature takes 1d10 lightning damage. 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.

Draconic Ancestory. You have resistance to lightning damage. You’re also acclimated to extreme heat, and you are considered naturally adapted to the heat.

Thirst for Knowledge. You have proficiency with one knowledge (intelligence) skill of your choice.

Protective Membrane. Your eyes have a secondary eye lid that is transparent, and protects you from being blinded. When you make a saving throw or skill check attempting to blind you, you roll that check with advantage.

Tremor Sense. You have unnaturally sensitive sense of touch, and when in contact with an object you can accurately tell where something moving is within 15ft of you. You have tremor sense out to 15ft.
