Two types of Armor:

  Body
    0 = none
    1 = leather
    2 = chain
    3 = breastplate or battle armor

  Shield
    0 = none
    1 = wood
    2 = plate

  Helmet
    0 = none
    1 = plate or battle armor

total_armor is the protection gained by the sum of both:

  Breast Plate gives -3 protection
  Chain mail gives -2 protection
  Leather gives -1 protection

  helmet gives -1 protection


Armor codes:                         Total_armor

000 = no armor                        -0
001 = leather body only               -1 
002 = chain mail only                 -2
003 = breat plate only                -3 
100 = plate helmet only               -1
101 = leather and plate helmet        -2
102 = chain and plate helmet          -3
103 = plate mail and plate helmet     -4 

-6 is the best with plate helmet, shield, and body armor.  This combination will restrict dexterity by 1.
