Combat With Armor (V7)
From AmtWiki
Armor (V7) is rated on its ability to stop blows. The rating ranges from 1 to 7 points, though some monsters can have more. The same damage rules apply to armor. Each strike will remove one point of value from the armor. Certain weapons and effects deal more damage to armor as noted in their descriptions. Damage only applies to the armor on the hit location that was struck. Armor only protects the area that it covers. Example: if you have armor on the front of your leg, but a gap on your thigh, then a strike to the location left open by the gap would wound you, though the armor itself would be unharmed.
