The copper used to make this cuirass makes it quite heavy, though it offers better protection than its counterpart made of leather. It is also no match for the durability of anything similar made of iron or mythril. Soldiers often use this piece of armor during their training for protection, as well as to train their bodies to support its weight. In other occasions, new recruits are sometimes teased by being made to carry a large number of these at a time.Final Fantasy Brave Exvius description
