Superior Dragon's Hide

Your resemblance towards your draconic ancestors has become near uncanny. You gain the following benefits:

• Increase your Strength, Constitution or Charisma score by 1, to a maximum of 20.
• Your scales become increasingly absorbent to the damage type of your ancestors. If you would take damage of the same type of your chosen draconic ancestor from a spell or otherwise magical effect, as a reaction, you can spend a number of hit die equal to your proficiency bonus, rolling them and gain that many temporary hit points before taking damage.
• Your claws become natural weapons of which you are proficient with. They deal 1d6 + your Strength modifier slashing damage, and an extra attack can be made with them using your bonus action if you used the Attack Action or cast a spell with a casting time of 1 Action.
