Unpiercable coat
''All armors remain weak against piercing blows: the finest weaponsmiths propose to craft a fine cloth of tiny metal rings which, linked together, would form an unpiercable coat that could be worn beneath other armors to protect against arrows and thrusting attacks. Such an armor would be expensive and really time consuming, requiring the best craftsmanship and metal, probably reserved to elite troops.''
