A bastard sword is a versatile weapon, so medium characters may wield it two-handed to deal 1 extra damage. Small characters must wield it two-handed, and they deal no extra damage for doing so.
No class has proficiency with the bastard sword as a class trait, but any character can become proficient by taking a Weapon Proficiency feat.
