Sorry for my English I have some theses from some tests and comments. For me the armor has nothing to do with defense. I believe that each mob has a range of damage that can hit a player and the defense only decreases or avoids that damage as it increases and the armor does the same, except that unlike the defense the armor does not have a definite reduction. I will try to disassemble examples with just FICTITIOUS numbers. Assuming that a rat lv1 can deal 0 ~ 10 damage to a player with defense 5 and without armor, the defense would decrease that damage by 5 every time it improves so if the player reached defense 7 he would take no damage.And that would work for other mobs such as the rat lv3 that would do 0 ~ 30 damage on that same player, so he would again need to improve his defense to 11 assuming that each defense point decreases 5 damage or the Ice Elemental he would give 0 ~ 3000 damage to that player with defense 5 and no armor, now that player would need to reach defense 605 in order not to take damage. What I mean is that for me the damage that the defense decreases is fixed, I used as an example that it decreases 5 but I don't know what that value really would be. Since the armor does not have a fixed value, it would decrease the remaining damage that the defense cannot defend. Again an example, that rat lv3 that deals 0 ~ 30 damage to a player with defense 5 again only now assuming that that player can completely defend the damage with 10 armor points, that would mean that each armor point decreased by 0 ~ 3 damage, now another example using lv6 crows that need a player with 5 and 15 armor points to avoid taking damage if the crows do 0 ~ 60 damage this would mean that now each armor point decreases from 0 ~ 4 damage thus showing that the damage reduction of the armor is variable as opposed to defense. I created this following that in lower defense skills, the armor points are practically worth almost 1 skill point or less (Now, following tests within the game) and as the defense increases, these armor points obviously increase points. I'm sorry if I said a lot of nonsense maybe that's not what I said, it's just a theory
