It's the heaviest armor, so far, in game. It's a very rare armor because the item required to obtain the armor can only be looted in a specific place.
This armor can block the same physical damage as Magic Plate Armor but only if you get physical hits of 119 or more, for that, the monster max melee should be 119x2 = 238 or more, wearing shield and other armors will reduce that damage so... you will have to fight stronger monsters to make your armor block as good as magic plate armor.
