Help: handedness

Right Handed
When you choose to be right handed, your right hand becomes your prominant
hand. You become less proficiant with your left hand. Hence weapons wielded
in your right hand would deal slightly more damage than average and weapons
wielded in your left hand will do slightly less than average.

Ambidexterous
When you choose ambidexterous, you gain the ability to use both of your
hands with equal skill. Since you spend time training with both hands,
neither will be as proficiant as if you trained just one, but likewise,
neither will be as lacking as if you had only been training the other.
Your attacks will be average.
