Strength
From Anarchy Online Wiki [AOWiki]
Strength
One of the six Primary Attributes or Abilities Anarchy Online characters are endowed with. Primary Attributes affect your other skills, the higher your primary attirbute the more benefit you will get in skills that use Strength as a dependency.
A character's strength represents how much physical force they can exert, conversely it is used as a basis for many melee weapon skills and as a basis for many types of heavy armor.
