In the armor section, it mentions masterwork armors. It mentions you have to have a minimum enhancement bonus, and mentions that the cost is included in the magic price.
So as far as I can tell, that means the second armor becomes +4, it turns into masterwork armor.
That's....um....really strong.
Let's take chainmail as an example. Normally it provides a +6 bonus. When you gain a +4 enhancement bonus, the armor turns into Forgemail, which provides a +9 bonus.
Overall, the bonus is 9 + 4 = 13. So the magic armor is added +7 to your AC!! That means without magic your taking hits 35% more often against equivalent monsters....which certainly is no small margin.
And now let's add in a +4 shield heavy shield, that's another +6 to AC.
That means the difference in hitting a shield guy vs a nonshield guy is 30%, and I don't see the nonshield guy getting that much of an extra bonus (a bit more damage, but nothing that compares to a 30% miss chance for AC and reflex).
And overall, for shield and armor combo, the magic is providing a +11 bonus, a 55% miss chance added in because of magic.
I keep thinking I'm missing something. There's got to be more to this masterwork armor thing, but it seems to work. So all I can say is, you will need magic armor to survive high levels, and sword/board seems to be the king now.
