9.3.13 THE ACROBATICS SKILL (Secondary)

Those who use Acrobatics cannot wear any armour heavier than leather; 
however, they train themselves in a variety of skills that enable them to 
train their muscles and reflexes to such a degree that they can reduce 
damage and completely avoid attacks. While this is mostly a defensive 
skill, its effectiveness should not be easily discounted.
