unmodified, they all should have 1 attack. But this no. is modified by weapon proficiency - if you have 2 or 3 stars in a weapon and the character is wielding that weapon you get an extra 0.5 attack. In addition, Rangers get an extra attack if they wield a weapon in one hand and they do NOT wield a shield in the other. Note that this is for melee weapons only, missile weapons use different rules.
