Whenever you make a Charisma check when interacting with dragons, your proficiency bonus is doubled if it applies to the check. Additionally, if you know the find familiar spell, you can choose to have your familiar take the form of a pseudodragon instead of one of the normal forms.

You have resistance to one type of damage, choosing from acid, cold, fire, lightning, or poison (your choice). This usually corresponds to the damage type dealt by your draconic parent.

You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

Choice of a draconic Ancestry will grant resistance to one type of damage. This will also affect description traits.

Alignment

Draconic bloodline does not affect character alignment. It is noted that gold and copper bloodlines do lean more toward good alignment..
