Okay, I'll ignore it for now, I was just wondering how it was dealt with since it said we had a defense value, and then didn't provide information on how to actually apply said defense value, such as how to decrease damage based on your defense. Which, if it was being used, would be important to know, since it could and would impact battles a bunch.

Well, considering that the novice starting armor provides 0 defense, the soonest it will be a factor for you is when you either loot some armor off a monster or hit level 5 and buy some basic stuff... or some gets made for you by either a tailor or blacksmith.
For now though, the entire armor value just gets taken off the damage roll... so say if someone did 40 damage to you, and you had 30 armor, you'd take 30 off the total and only take 10.
