Mount&Blade: With Fire & Sword/Proficiencies

The proficiency rating of weapons will determine how well you can hit with a weapon (dealing more damage and having greater speed) as well helping you aim with ranged weapons.

You can gain weapon proficiency points by using that type of weapon in combat or by spending weapon points each time you level up.

If you add a point to agility you will get +5 extra points to add to your proficiency.

Note that you will have to keep your weaponmaster attribute high in order to train faster. The higher this attribute is, the less points you need to spend for each level.
