It seems that most cultures have one thing in common, a need for warriors. These are the men and women who train from birth to survive the lethal environment of close combat with weapons and armor. These soldiers, mercenaries, guards, etc. utilize their knowledge of armor, weapons, and tactics to great effect. While they may not have a lot of skills with which to draw from, the skills they do learn are extremely effective, and are generally learned quite early. The only drawback of the warrior lies in its main strength, its simplicity.
The prime requisite of Warriors is strength giving them the capacity to mete out more damage, and carry more gear and equipment than any other class.
