Magic Plate Armor, also commonly known as "MPA" or "e-plate" (Enchanted Plate Armor), is the third best armor in Tibia for knights and known to be cheaper in older Game Worlds. After Christmas Update 2008, this armor became for knights and paladins only. On the Winter Update 2011, the Ornate Chestplate was introduced with an armor value 16, a bonus of 3 extra shielding skills and 8% protection to physical, but it's only for knights level 200 or higher. However, another better armor than this is the Royal Draken Mail, which is more acessible nowadays.
