Draconblood

Draconbloods possess long tails and a knack for social manipulation. They remember the days when they were once mighty conquerors.
A draconblood uses the dragonborn traits in the Player's Handbook, with the following traits replacing the Ability Score Increase and Damage Resistance traits.

ability score increase: Your Intelligence score increases by 2, and your Charisma score increases by 1.

age: Young dragonborn grow quickly. They walk hours after hatching, attain the size and development of a 10-year-old human child by the age of 3, and reach adulthood by 15. They live to be around 80.

alignment: Dragonborn tend towards extremes, making a conscious choice for one side or the other between Good and Evil (represented by Bahamut and Tiamat, respectively). More side with Bahamut than Tiamat (whose non-dragon followers are mostly kobolds), but villainous dragonborn can be quite terrible indeed. Some rare few choose to devote themselves to lesser dragon deities, such as Chronepsis (Neutral), and fewer still choose to worship Io, the Ninefold Dragon, who is all alignments at once.

Size: Medium

speed: Your base walking speed is 30 feet.
