@ChrisPerkinsDnD A "Dragon Slayer" sword says it affects any kind of dragon… Are Dragonborns affected by it too with extra damage?

Dragonborn are technically humanoids, not dragons, but a DM might allow it. #WOTCstaff https://t.co/vBdfNdYC9Z

Yes actually dragon borns are considered dragons in the official book it says dragon borns are born from a dragon egg and are a rare subspecies of dragon that only happens every so often
