The pre-gen for Level 1 Amiri shows her wielding a bastard sword with two hands for 2d8+4 damage. I know that Exotic Weapon: Bastard Sword allows you to wield the sword one-handed for 1d10 damage and that if you do not have this feat, you need to wield it two-handed to get 1d10 damage. Where in the rules does it state that Exotic Weapon: Bastard Sword allows a bastard sword to do 2d8 damage when wielded two-handed?
