Can dual-wield?
Any character can wield two weapons, but he’ll have significant attack penalties if he doesn’t have the right support feats and equipment. These feats are available to all classes. Rangers get most of them automatically as they gain levels. The best case requires taking the Two Weapon Fighting feat and making sure the weapon in your off-hand is a small, easily-handled light weapon. Even in this situation, you have a -2 penalty to both your hands. If you don’t use a light off-hand weapon (and you don’t have the Oversized Two Weapon Fighting feat, which removes the light weapon requirement), you suffer an additional -2 to both hands. If you don’t have Two Weapon Fighting, you’ll have -2 to your main hand attacks and -6 to your off-hand attacks. These penalties are independent and cumulative.
