Magical armour is very rare and valuable. Magical armour and shields confer extra armour points - either +1, +2, or +3 armour points according to the strength of the enchantment. Mithril armour is not in itself magical, but the wonderous silver metal is so tough that it cannot be worked except by magical means. It is also very light and armour made from it weighs 20% of normal (20% encumbrance). Mithril armour gives one additional armour point.
