We've included two cards representing magic armour: Armour of Meteoric Iron and the Enchanted Shield. Wizards cannot wear armor because it interferes with their magical senses and makes it impossible for them to cast spells. Other characters can wear magic armour and benefit from its protection. Magic armour either replaces ordinary armour entirely or supplements it as you will see from the two examples. A character cannot wear ordinary armour and the equivalent magical armour on top!
The Armour of Meteoric Iron comprises an entire suit of armour including a shield and gives its wearer an armour save of 2+. This is better than normal heavy armour and shield which would give a save of only 4+. If the wearer were riding a horse his save would improve to 1+, but it can never be better than 1+... 1+ is the best save you can get! The Enchanted Shield can be carried in conjunction with ordinary armor instead of an ordinary shield and gives a saving throw of 5+ rather than 6+ like an ordinary shield. If combined with heavy armour it therefore gives a save of 3+ rather than 4+.
