Draconic Constitution

You have a deeper understanding of your Draconic Ancestry than most Dragonborn, and have used this knowledge and experience to strengthen your own scaled hide to protect against your own ancestral element.  You gain the following benefits:

• Increase your Constitution score by 1, to a maximum of 20.
• You have immunity to the damage type of your Draconic Ancestry.

(Note for D&D Beyond Character Sheet Users: You must manually convert the resistance of your Draconic Ancestry into an Immunity when you add this feat. Constitution increase will take effect as normal when the feat is added.)
