This system is based on the premis that characters may try to use weapons either 1 handed or 2 handed, and may have some amount of success. Wherever the damage is not applicable (n/a) it means the damage would be the same or it is impossible to use the weapon this way. The number in parenthesis is the bonus to hit roll.
