Mount&Blade/Attributes

There are four attributes. Each has its own specific purposes, so you'll probably want to advance all of them to fully develop your character. Except at creation, you only gain one point per level to distribute. Attributes also determine how much you can advance an individual skill.

The following skills cannot be developed beyond ⅓ of Strength:
 * Ironflesh
 * Power Strike

Agility
Each point to Agility speeds up a character's attacks by 0.5% and adds 5 weapon proficiency points.
